Judging by the style of clothing and the four-panel continuity, this is probably a reprint of two late fifties to early sixties era Archie syndicated newspaper strips.
Credits were added to this story when it was reprinted in "Archie Giant Series" in 1980.
Letters from E.F. (Tucson, AZ), M.L.B. (Winnipeg, Manitoba), and J.S. (Kingston, NY).
Ad art is the same for the ads for Laugh Digest #5 and #6.
