Planet Comics
"Planet Comics" #1 was released with a cover-date of January 1940, and ran for 73 issues until Winter 1953. Initially produced on a monthly schedule, issue #8 (September 1940) saw it slip to a bimonthly title, which it held until the end of 1949. From issue #26 (September 1943), "Planet Comics was cut to 60 pages," resulting in the merging of two strips: Flint Baker and Reef Ryan. Issue #63 (Winter 1949) began a quarterly release schedule, but #64, #65, and #66 were ultimately released annually, dated Spring 1950, 1951, and 1952, respectively. Issue #67 (Summer 1952) got the comic back on its quarterly release schedule, but the title only lasted a further seven issues, with its last (#73) again delayed for over a year, following issue #72 (Fall 1953).
