Anyone recognize this (German) exchange club from 1932 ?
The red rubber stamp says he is member of "Internationale Tauschvereinigung"
on right side says: Mitglied Nr. 6480, on left side says "...stein"
The sender is from Nisny-Nowgorod USSR, and mailed to Syria.
Asks in mixture of German and English "Karte mit stamps of Syria"
The card shows Feodosia (old Caffa, nice place)
