Archie, Veronica & Betty were part of an effort by Topps to make the kids from Riverdale as iconic on Blony bubble gum comics as Bazooka Joe and His Gang were on their turf. In fact, in 1957-58 Blony comics featured the Archie comics gang but it would be another decade or so before Archie became a TV star and despite Topps' best efforts, Blony Gum would not last as a brand past the early 60's (save for a later attempt to market it as a twist wrap in the 70's, also a failure).
