In my overview of the Federal Marvel advertisements I began with the Professor Teddy Woods ad which appeared on issues dated up to August 1984.
Of course Federal's DC reprints had been up and running for well over a year earlier, and they begin with this advertisement on the rear cover:
Murray the Cat Fan Club
April 1983-November 1983
Federal Comics DC issues with this advertisement on the rear cover will date between April-November 1983 - possibly also December 1983, which I will cover in a separate entry.
This advertisement crosses over two different Federal imprint logos - the Murray the Cat/Federal transitional logo and the red FC logo. I will also cover the logos in a separate entry.
After the Professor Teddy Woods ad took over rear cover duties the following ad could be found on inner covers of Federal Comics DC issues:
It is identical to the blue ad and it appeared in issues dated up to May 1984, by which time the black DC Australian Edition logo was in play.
