In 1927, the J. H. Warder Company of Chicago released Tu-Tee, and the Charles Bowlby Company released Cootie; though based on a "build a bug" concept similar to Schaper's, both were paper and pencil games. In 1937, Rork's released The Game of Cootie, and it too was a paper and pencil game. A paper and pencil party game called Beetle is popular in Britain, and dates from the mid 1940s or earlier.
