Beginning in the 1930s, inexpensive jigsaw puzzles came into favor as entertainment. People were impoverished by the Great Depression and could afford little in the way of luxuries. Hundreds of paperboard puzzles were produced and sold at newstands, usually a new one every week. The puzzle mania began around Boston and spread across America and Canada. Consolidated Paper Box Company, makers of Perfect Picture Puzzles, was one of the biggest manufacturers. The fad lasted into the 1960s when tvs became common.
There are a number of websites that are a good source of information for vintage picture puzzle collectors. A few good examples include; Tuco Puzzle Site, Puzzle History, Perfect Picture Puzzle, Antique Jigsaw Puzzles and Jardin Puzzles.
