Often on Ebay “North Korean” revenue stamps show up. The provenance of these stamps is “unknown” at best, but given that these stamps are never seen used on real documents from North Korea it is likely these stamps are fake. Or are they? Here is a picture of an item offered on Ebay somewhere in the last year (I forgot to write down the details…). If I remember correctly the asking price was rather steep, so I didn’t bid on this item, but it is historically very interesting for revenue stamp collectors and I did save the pictures before the item disappeared from the Ebay listings.
The front shows the coastline of North Korea, with a train riding along the coast. The back shows a text written in either Czech or Slovakian, but probably Czech since the city mentioned in the address is Boleslav, a small city in current Czech Republic (but then still undivided as Czechoslovakia) very close to the German border. The name of Czechoslovakia is written both in Cyrillic as well as in Hangul. The stamps used are (from left to right) three normal postage stamps (2 won, Scott 40; 10 won, Scott 50; 20 won, Scott 49) plus 2 revenue stamps, a red one of 1 won and a brown one of 5 won. Only the brown revenue stamps is listed in the Barefoot revenue catalogue. I can’t read the date in the cancellations (except for a few Cyrillic characters), but since the Scott 50 is from April 1952 this card should be from around that time.
