My real interest in these is that they catalog the German tobacco cards quite nicely. These cards were originally issued with packs of cigarettes. Eventually, coupons were added to the packs instead of the actual cards and they the buyer could then redeem so many coupons for packets of cards (issued in groups called Gruppe to stick in albums. It seems about 5-10 packets of cards would complete 200-300 card sets so each Gruppe packet held about 20-30 cards. It is more common than not to find albums with all the cards glued into the albums. Here is an example I pulled from the internet:
This particular set is the Deutsche Volkstrachten which appears to be cards of people from all over Germany. According to Koberich, this set was made in 1933 by Eckstein, a cigarette manufacturer out of Dresden. The catalog number is #20502-12...this was the 12th set they produced and it has 198 cards. Pretty cool.
Once I hit up some more flea markets, I'll post my finds. Cheers and I hope everyone enjoys there weekend!
