This issue is a variant of Tarzan (Marvel, 1977 series) #18 [newsstand].
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.
