Notes:
Remington Morse was part of Hamilton Ross's group of companies, the first of which was founded in 1921. Remington Morse itself was founded in 1943. The consensus seems to be that it published comics only in 1943-44, although no dates appear on the comics themselves. A "Remington-Morse Mother Goose and Father Gander" book was published in a 2nd edition copyright 1945 (after a 1st copyright 1943-44), so the company continued at least a little while longer.
