It is refreshing to see something you never knew existed. A little-known firm, Frank T. Riley Publishing, issued this set of twenty-five fortune cards. The envelope's art work is vaguely interesting and seems to have been replicated on all cards, based on the only two extant with this listing. Normally, I'd be all over this kind of item, given that my far-and-away favorite sub-genre of vintage Halloween memorabilia is paper, but this is too rough and incomplete to tempt me much. It'll be instructive to see what it brings.
