Scott #Q1 Dark Carmine [1913 1c Parcel Post, Postal Clerk Sorting Packages] Used with Fine centering and very light cancellation. Natural straight edge and guideline at right, from the right column of a left pane.Scott #Q1-12 were printed in sheets of 180 consisting of 10 columns and 18 rows, divided by cutting along guidelines into four panes of 45, consisting of 5 columns and 9 rows. The cutting often seems to have been done on one side or the other of the guideline, resulting in some straight edge examples bearing 100% of the guideline and its mate from the adjacent pane bearing no guideline. The guidelines terminate in arrows in the outer perforated pane margins (not normally on the stamps) on all four sides; arrow-margin examples are hard to find. Including the 4 corner positions at the center of the 180-sheet, 18 stamps out of every 180-sheet had the natural straight edge and guideline at the right (and same for at left). Including the 4 corner positions at the center of the 180-sheet, 10 stamps out of every 180-sheet had the natural straight edge and guideline at the top (and same for at bottom). Examples with a one straight edge, end especially corner straight edge positions, are now hard to find and mostly come from old collections. (Most straight edge and guideline stamps were used for postage rather than going into collections; and of those that remained, many have been reperforated to remove the straight edge.) I think that collecting the guideline and straight-edge positions is quite challenging and rewarding. An attractive example. This right straight edge / guideline position from the printer sheet represents only 16 out of 180 stamps printed, but far fewer than that can still exist today.
