I picked these up on ebay. They were listed as 1920's indian ice cream cards, but I suspect they are not but had never seen this type. Cards are 2 1/2" x 3 1/2" and blank backed I asked the seller about them could not get much information other than they might be referenced in the Benjamin guide, but I cannot find anything there that matches up.
Would be grateful for any information on these. The artwork type and font remind me more of late 1800's game cards.
