Thanks, Pete, your information will help a LOT on some of them!! (I hope! )

There's one helpful piece of information that you could add to it....

On the Curt Teich (or C.T. Art-Colortone) there's an alpha-numeric date code. Sometimes it's on the front, sometimes on the back, sometimes in the stamp box.

The "alpha" part indicates the decade
A=1930's
B=1940's
C=1950's
D-1960's

The numeric part indicates the year....so 7A would be 1937, 5C would be 1955, etc. The date code is followed by another number, which I suppose relates to the scene.

I sure do like it when they're postmarked!!!!
