The following is an excerpt from BGG page on Cadaco,
"In 1940, on the eve of World War II, YANKEE DOODLE became a popular CADACO game, and was copyrighted by Ellis and another CADACO employee, Crandall. Crandall was related to C. Leslie Crandall, a Bohemian artist who did much of the artwork for CADACO-ELLIS games and was a partner until the company was later sold.
The following is from the website:
In 1940, YANKEE DOODLE became a popular game, judging by the number of copies that are still around today. Historians will note that the copyright was by Crandall & Ellis. Crandall was not related to the famous name connected with blocks and with E.G. Selchow (PIGS IN CLOVER), but was C. Leslie Crandall, a bohemian artist in San Francisco who did much of the artwork for Cadaco-Ellis, becoming a partner around the late ‘30s until the 1960s when the company was sold.
