I came across information on a Star Wars newspaper comic strip which had Boba in it.
The following is pasted from the site concerning the timeline of the newspaper comic.From http://www.retrojunk.com/details_articles/703
"The strip began on Sunday, March 11, 1979, written and illustrated by adventure strip legend Russ Manning, appearing in the LA Times Syndicate. It ran for five years (until 1984), and comprised 27 story arcs. There were some great (and some downright silly) stories in that run, but perhaps the greatest and goofiest is the ninth story arc, "The Frozen World of Ota", which ran from June 17 to August 10, 1980.
The Empire Strikes Back premiered a month before this storyline started appearing in the morning papers, on May 21. So by that stage audiences had gotten the dose of Boba Fett that they had been hungering for in the years building up to the sequel. Of course, in those days there weren't synchronised worlwide releases, so in Australia for instance (where ESB was released on August 7, 1980), fans would have been reading about Fett in the newspaper strip in the lead-up to actually seeing the movie."
Here is one one photos form the site of the artwork.Notice the color scheme of his outfit.
The web article is a pretty good read as far as research into the different ways Boba has "poped" in and out of entertainment outlets.
