In honor of the first day of July, this is the cover of the July 1951 issue of Playthings Magazine, THE industry magazine of the toy trade. Collectors love these magazines because they are chock full of articles and advertisements for lots of vintage toys. And from the 1930s-1950s, every cover featured Disney characters.
For most of 1951 the covers featured Alice in Wonderland characters. This issue is special in that it advertises the 1951 character merchandise catalog. Character merchandise catalogs of any year are scarce, but the catalog for 1951 (the final year of the catalogs) is especially so.
