thought the same thing myself. Matter of fact recently I have read some Marvel(Atlas) and DC romance books from this same era and The quality of the books and art , IMO, is way better than Avon, Charlton, Harvey, Ace, etc. in Those old atlas/dc books color registration was not an issue and the art was better (my measurement for that is in how classically beautiful or handsome the characters are.) I'm sure there are reasons aplenty for why most publishers did not survive the implementation of the code, but I have to think that at least to some degree , Marvel(Atlas) and DC's consistent quality of product had to give them a bit of an edge.
