This issue is a variant of Star Wars (Marvel, 1977 series) #10 [Regular Edition].
Variants of this type were distributed under limited deals between publishers and distribution "jobbers" (Whitman was one, but not the only one) who could get comics into outlets that did not consistently carry comics. The retail unit was a bag containing more than one comic.
Tony DeZuniga inks credit confirmed by Rick Hoberg via Shaun Clancy (19 May 2015). Original inks credit was given to Rick Hoberg.
Letters from Mike Heisler, Burton Glass, Rod Richards, Pammi Bowen, Nancy E. Porter; includes Roy Thomas' farewell editorial as he stepped down as series writer.
