Superboy and the Legion of Super-Heroes #4: The Federal edition

Federal Comics' Superboy and the Legion of Super-Heroes #4 was published c.January 1984. It's a rather anomalous issue and its publication appears to have been delayed.

The series began as Super Heroes in late 1982. Murray Comics published the first issue; the second was published by Federal comics under the transitional Murray the Cat/Federal Comics logo and cover-dated March-April 1983; and the third issue was published by Federal Comics c.July/August 1983.

Federal Comics' one-shot issue The Flash was also published c.July 1983, so it would have been on  newsagency stands at the same time as Super-Heroes #3. The final page of this issue advised that the Flash story Mishmash would be Next in Super Heroes #4:

 By the time Mishmash!! appeared six months had elapsed and the series had changed its name.

The final page of Mishmash!! advises the story is To Be Continued in.. Batman and The Flash:

This issue was published as Batman and The Flash #6 in February 1984, a month after Superboy and the Legion of Super-Heroes #4.

Given the next issues were advertised it suggests the preparation of these issues was well on the way. For this reason I believe Superboy and the Legion of Super-Heroes #4 was delayed.

The new series title did not last beyond this issue. By the fifth issue the series title was shortened and Legion of Super-Heroes #5 appeared c.April 1984 some nine months later. Maybe this wasn't so confusing in 1983/84 but when I first started collecting Australian reprints it took me quite a while to place it in this rather confusing continuum of series titles and logos. And that's without mentioning the Planet Comics iteration of Super Heroes/Album - a mishmash indeed!
