AVENGERS #155

Cover shows strong gloss and vivid color with sharp corners and no visible creases or spine stress lines. There is minor edge wear at the top and bottom corners and a slight bend visible near the lower right edge under the protective sleeve. The book is in a plastic sleeve which causes some glare, slightly obscuring fine surface detail; interior pages and back cover were not assessed.

Avengers #155 is a mid-1970s team-book chapter written by Gerry Conway pitting the roster against the undersea warlord Attuma alongside a gathering of familiar adversaries including Doctor Doom, Baron Zemo's Enchantress and Executioner, set against the ongoing Bronze Age churn of the Avengers' rogues' gallery. Its chief point of interest for collectors is the presence of George Pérez on pencils early in his career, inked by Pablo Marcos, with a cover credited to both Al Milgrom and Jack Kirby; the issue carries no first appearance, origin, or landmark creative milestone and is not considered a key by any standard price guide.

Market data shows a typical long-tail Bronze Age distribution: certified population is substantial (151 Universal copies across 164 total graded), with values climbing sharply only at the top of the census. Mid-grade copies trade in the low double digits, reflecting steady but unspectacular collector interest tied mainly to team-book completism and Pérez's early art rather than any narrative milestone, while the 9.8 tier commands a real premium driven by relative scarcity at that grade (33 census copies) against demand from Avengers run-builders and Pérez collectors.

This is a book acquired to complete a run or a Pérez bibliography rather than pursued as a standalone investment. Raw copies in low and mid grades move slowly and cheaply, largely absorbed by longbox and reading-copy buyers, while CGC 9.8 examples see genuine competitive bidding among condition-census chasers, producing the outsized gap between raw and top-slab pricing typical of common Bronze Age issues with a notable but not headline-making creative team.
