As a longtime record collector I could not avoid similar experiences (there are obviously more collectors here in the forum). Just recently bought a vinyl on Concord Jazz vinyl "The Jazz Giants live from Switzerland" issued with complete different cover and found out I have the japanese EmArCy reissue for years on the shelf. It is necessary to check the content (tracks) first if you have a bigger collection. From that Fresh Sound vinyl era you have mentioned I have a good bunch of Items bought here in Germany becaus the US originals were long oop and Jordi Pujol had started the reissues later on CD's only.
The problem for trading vinyl is you can do it only here with european collectors. The postage for sending a vinyl to the US is pure robbery .
