3M bookshelf game series

The 3M bookshelf game series was a series of board games produced by 3M from 1962 to 1975. These games were marketed towards adults and were designed to fit onto a standard bookshelf. Each game fit into a slip cover that was made to resemble the spine of a hardcover book. 3M's catalog described them as "[b]ookcase games, packaged in attractive leather-like slipcases, make a handsome set of volumes for any bookshelf."
