206 [1924 50 öre UPU Congress] Mint, lightly hinged, with F-VF centering, but some blunted perforations on right (typical for this issue). This example shows a plate join line on the left side perforation tips. [Plate join lines on the UPU Congress and Anniversary are quite interesting. Printed on the rotary Stickney press -- same as the USA used at that time -- the printing cylinder for the UPU stamps consisted of two half-cylinder 40-stamp printing plates; the plate join lines occur in the two locations that those two plates meet. In the definitive work "Postage Stamps of Sweden 1920-1945" by Menzinsky (1946), published by the Swedish post office, the author states that only one (half-cylinder) plate was made for each stamp, respectively in the Congress issue and the Anniversary issue, and that, for each denomination (thus color), those two half-cylinder plates (of the two different stamp issues) were mounted on the printing cylinder, thus each full revolution of the printing cylinder produced 40 of each of the two different stamps of a particular denomination. The web containing the sheets of the two different stamps was very soon after separated along the perforations at the plate join line, thus while there maybe combination pairs existing in the Swedish Postal Museum, no such pairs are available to collectors. Because of this printing / plate layout, the horizontal-format stamps (öre denominations) cannot exist with sheet margin on the left or right sides. Likewise, the vertical-format stamps (kroner denominations) cannot exist with sheet margins at the top or bottom. For every denomination of both stamp issues, examples with plate join line exist on both left and right sides of the öre denominations and both top and bottom of the kroner denominations. A comprehensive specialized collection could thus include examples of both for each stamp. A MYSTERY YET TO BE ADDRESSED IS: Since each half of the printing cylinder resulted in printing stamps of the two different issues, Congress and Anniversary, WHY ARE THE ISSUE QUANTITIES SOMETIMES SIGNIFICANTLY DIFFERENT for the two same-denomination stamps of the two different issues? Were both printed in the same quantities but many stamps were later destroyed?] Very fresh example, priced very low. |

211 [1924 5 kr UPU Congress] Mint, modestly hinged, with VF-XF centering, but with a light crease at the top (only visible from the reverse). This example shows a plate join line on the top perforation tips along with slightly blunted perforation tips as is usually associated with these pane-edge stamps. Plate join lines on the UPU Congress and UPU Anniversary issues are quite interesting. They were printed on the rotary Stickney printing press -- the same type of printing press that was used in the USA used in that time period. The printing cylinder for the UPU stamps consisted of two half-cylinder 40-stamp printing plates; The plate join lines occur in the two locations where those two plates meet. Though remnants of the plate join line can appear on the perforation tips of both previously-joined stamps, often, because of poor placement of the perforations (poor centering), the plate join line is only visible on the perforations of one of the two previously-joined stamps. This fact, combined with reperforation to remove remnants of the line or collectors having used up such stamps for postage instead of collecting them, has resulted in the plate join line examples now being somewhat hard to find. In the definitive work "Postage Stamps of Sweden 1920-1945" by Menzinsky (1946), published by the Swedish post office, the author states that only one (half-cylinder) plate was made for each stamp, respectively in the Congress issue and the Anniversary issue, and that, for each denomination (thus each color), those two half-cylinder plates (of the two different stamp issues) were mounted on the one printing cylinder, thus each full revolution of the printing cylinder produced 40 of each of the two different stamps of a particular color / denomination. The web containing the sheets of the two different stamps was then manually separated, by tearing, into panes along the perforations at the plate join line, often resulting in slightly blunted perforations. Thus, while there maybe combination pairs existing in the Swedish Postal Museum, no such pairs are available to collectors. Because of this printing / plate layout, the horizontal-format stamps (öre denominations) cannot exist with sheet margin selvage on the left or right sides. Likewise, the vertical-format stamps (kroner denominations) cannot exist with sheet margin selvage at the top or bottom. For every denomination of both stamp issues, examples with plate join line exist on both left and right sides of the öre denominations and both top and bottom of the kroner denominations. A comprehensive specialized collection could thus include examples of both for each stamp. [A MYSTERY YET TO BE ADDRESSED IS: Since each half of the printing cylinder resulted in printing stamps of the two different issues, Congress and Anniversary, WHY ARE THE ISSUE QUANTITIES SOMETIMES SIGNIFICANTLY DIFFERENT for the two same-denomination stamps of the two different issues? Were both printed in the same quantities but many stamps were later destroyed?] Great color, excellent perforations on three sides, plus the usual perfs along the line at top, and very fresh appearance. Otherwise would be $210 for this centering! |

225 [1924 1 kr UPU Anniversary] Used VF right-marginal 4-BLOCK with neat light central cancellation, large margins, and excellent perforations. The left two stamps have noticeable gum-soak staining (the gum soaked into the paper, making it slightly translucent); this is only barely noticeable on the right two stamps (and if removed from the block, the right two stamps would look normal). A very attractive accent piece; used blocks of the high values are seldom seen. Priced mostly for the right two stamps. |
