I think it's no coincidence that Hart Amos did the humour content of this first issue of Devil Doone - I believe he was already the Devil artist on the first-published version of the stories in Man Junior at this time. Between Carl Lyon, June Mendoza and Hart Amos, the series has great quality in the art department, though obviously different from each other. BTW, my introduction to Australia's Golden Age was similarly through a reprint: I got an issue of Catman in a sample bag at Sydney's Royal Easter Show. Not sure which one - the last four issues of Catman all reprinted the same story, about a year apart from each other
