In 1949-1952 Don Heck worked in production, cutting and pasting strips for re-publication in the comic book format and doing art corrections. The publication dates, as reported by Harvey during 1964 and 1965, were listed as being published on the 15th day of each month. Actual publication/on-sale dates varied though and could be up to 21 days earlier than the publication date reported to the Copyright Office.
