Each of the Sunday's listed below measure approximately 21 X 15. Please note that in the 60's to mid-70's it was the practice of Tribune Media Services to take the originals sent to the syndicate and after cutting them up, glue them on a backing board in the half-page format you see in the scans below. This was a practice used not only for On Stage, but other TMS comic strips like Gray's Little Orphan Annie and Gould's Dick Tracy.
