K & M Company
The small albums with team logos were sold at Toys R' Us and other stores around 1974 and were the first sheets, as I recall, that were designed just for baseball cards. They were produced by K & M Company in Southern California. Initially only 9 pocket side loaders were made for standard cards. Around a year or two later a collector from Tennessee (Gene Lebo) marketed plastic 'wall hangers' which fit 1950's cards. I think I still have one or two of those, but they were very impractical......... Prior to these 'card' sheets, I can recall using sheets / albums designed for photos which were sold at a local drug store. The cards slipped around like a nail in an otherwise empty Cracker Jack box.... It sure beat putting cards in those photo albums with the peel back plastic and adhesive lines which ruined many collections over the years...
