I would just like to comment positively on Titusfan's efforts to bring us all these give-aways and other promotional comics. I would like to comment om most of them, but somehow the comment button has disappeared from my pages. Anyway, the last one, The Story of Mass Production, is about the best sample of Creig Flessel's work at that time I have ever seen. Therefore I suspect it must be by Johnstone and Cushing, where Flessel was exclusively. J&C regular Dik Browne used to do cartoons for the Ford magazines so the connection is easily made.
