The Empire Strikes Back Monthly number 150 represents the 150th installment in the The Empire Strikes Back Monthly comic reprint collection, hitting shelves in September of 1981.
The cover hints at the inclusion of the first part of "The Pandora Effect", however, an announcement on the opening page explains that due to deadline issues, it couldn't be included in this particular issue. Consequently, it features a reprint of Star Wars (1977) 16 instead. "The Pandora Effect" eventually appeared in full in the subsequent issue, The Empire Strikes Back Monthly 151.
