Foreign cancellations on Icelandic stamps are largely the result of mail handed directly to fishing boats and small cargo ships or letters written by sailors on those vessels. When the next port of call was another country (typically Denmark, Norway, and the United Kingdom) the postmark of that country was applied. In the case of Denmark, this was often the "FRA ISLAND" (from Iceland) incoming ship mail cancellation.
All items may be viewed on approval; approval groups of foreign cancellations on Icelandic stamps are also available.
28a Ultramarine [1896 20 aur Numeral, Perf 12.75] Used F-VF, couple slightly shorter perf tips, with partial (ST)AVANGE(R) bridge type cancellation (applied on incoming ship mail likely posted at sea on an Icelandic fishing trawler). Date of cancel is unclear, but looks like 1903. Stavanger is unusual this early. Scarcer stamp color.
