1960s Crooked Gambling Catalog
Forrest Flanders, collector of old catalogs of every stripe, has put a complete set of scans of the the old K.C. Card Company Blue Book up Flickr. Until the 1960s, it was legal to sell crooked gambling equipment. Along with the H.C. Evans Company in Chicago, the KC Card Company (also in Chicago) was one of the major U.S. providers of gaffed cards and dice, as well as various various carnival games. Forrest has scanned each page of the company's 1960 catalog, and offers them in a variety of resolutions. I could spend all day perusing these scans.
Also: If you are the kind of person that feels the need to own an original catalog, you can find it here at Earth's Largest Magic Shop. Tell 'em Jim Morton sent you.
