I have just purchased a large number of postcards, so the ones that I don't need are all for sale.
There are over 2700 different cards from hundreds of airlines, a mixture of airline issue and publisher cards and including lots of Russian types, propliners and airlines no longer in existence. There are also some General Aviation cards, some airport cards and some military cards.
Prices vary depending on how many you buy, plus postage from the UK on top:
1-10 cards £0.35 each
11-99 cards £0.30 each
100 + cards £0.25 each
If you don't know me, I sell on ebay as ms190876 and have 100% feedback there.
If you want to see the list, please drop me an e-mail to firstname.lastname@example.org
