1891, Insufficiently prepaid letter sent September 15th from the Falkland Islands to Stockholm. The Falkland Islands became a member of the UPU on January 1st 1879. The paid rate was 4 d on the islands and as the letter was franked with 2 1/2d, the missing postage was 1 1/2 d which corresponded to 15 centimes and should have been marked as "15" to the left of the stamp according to UPU rules. However as the postmaster missed to do this, the postmaster in Stockholm regarded the letter as originating from Great Britain and debited the addressee 40 öre (2x 20 öre postage due stamped pair on reverse on envelope cancelled Stockholm KK 20.10.1891) which was the UPU rate from Great Britain. This letter is the only one known from the Falkland Islands with postage due stamps. Certificate HOW (2009) The left stamp is repaired on the left side.
