MARVEL TEAM-UP #55

Cover shows strong gloss and vivid color with sharp corners; no visible creases or color breaks in this photo. Slight whitening/wear is visible at the top-left corner tip and along the spine edge near the top, and the book is housed in a protective sleeve which limits full assessment. No tears, stains, or writing are visible on the front cover. Interior pages and back cover were not assessed.

Marvel Team-Up #55 continues the loose multi-issue Bronze Age arc pairing Spider-Man with Adam Warlock, a character then enjoying a modest resurgence in guest-star appearances across the Marvel line. Scripted by Bill Mantlo with pencils by a young John Byrne (inked by Dave Hunt) and a Dave Cockrum cover, the issue pits the heroes against the cosmic Stranger and the brute-strength creation Woodgod, with Doctor Octopus and Gardener rounding out the supporting cast. The book carries no first appearance, death, or origin story, and its significance rests chiefly on its early Byrne art and the Warlock crossover appeal rather than any landmark event.

Market data shows a typical Bronze Age demand curve: raw and mid-grade copies trade for modest sums reflecting ample supply, while values climb sharply only at the top of the census. The jump from the mid-nine grades into 9.6 and especially 9.8 is pronounced, driven by a thin pool of pristine newsstand survivors rather than any inherent scarcity of the issue itself. Demand is concentrated among Byrne-art completists, Warlock character collectors, and Marvel Team-Up run builders rather than broad key-issue speculation.

This is a book that trades steadily but unremarkably in low and mid grades, serving as filler for long-box collections and team-up run sets. Its real trading activity is concentrated at the high end, where CGC 9.8 census copies command outsized premiums purely on condition rarity. Collectors assembling complete Byrne bibliographies or Adam Warlock cross-title runs are the primary buyers; general Spider-Man collectors are unlikely to prioritize this issue outside of a complete series run.
