From 1949 until the mid-fifties this company had some notable comics. They were able to obtain the rights to some famous characters including Felix the Cat, Buck Rogers, Li'l Abner and other Al Capp spin offs. Unfortunately those books are probably not PD and should not be directly uploaded. Toby did publish many other books in most genres, except superhero, and most of those should be fine here.
NOTE - the following titles/characters are NOT public domain. Please do NOT upload any -
Felix and his friends
Felix the Cat or any other Felix titles
Nothing with King Features material if there are any titles with reprints
Al Capp titles - especially Li'l Abner
Any Terry Toons
