The top card (with the soldiers) is from 1943
The center card (with the Indian) is from 1934

You can date most linen cards by the code that's stamped on them. Your top 2 cards both have it in the lower right corner, some cards have it in the stamp box, next to the stamp box, or somewhere else on the card.

Use the first digit of the code and the letter that follows it. The digit is the year, and the letter is the decade.

A=1930
B=1940
C=1950
D=1960

So the Indian card code starts "4A"...1934
The soldier card starts "3B"...1943

This works on all Curt-Teich cards

Thanks again for showing 'em!
