[buymycards]

Hi, I am hoping that someone can help me identify these. I have 21 of these cards, which are approximately 1 5/8" x 2 1/16. They have the same fronts as the 1950 JCM21 Menko's, but the backs are blank. The ones that are listed on eBay have backs similar to the back of a playing card. The other Japanese cards that I have had over the years were thicker than American cards, but these are thinner.

Any help will be appreciated. Thanks much! Rick
