1885, Insufficiently prepaid double rate letter sent September 30th from Pueblo (USA) to Åmot. Postage due was double the missing postage = 25 centimes as stamped on the letter. Instead of the actual UPU conversion rate the exchange post office used the old GPU conversion tables based on the commercial rate 1 centimes = 0,72 öre and the postage due became 50 x 0,72 = 36 öre. Thus franked on reverse, 1 + 3 + 12 + 20 öre adhesives cancelled "ÅMOT 22.10.1885". Slightly soiled letter opened up for display.
