MARVEL TEAM-UP #23

Cover shows strong gloss and vibrant color with sharp, well-defined corners and no visible creases or color breaks. Spine appears tight with only minor, faint stress lines near the top. Slight edge wear is visible along the bottom left corner, and the book is protected in a clear plastic sleeve. Interior pages and back cover were not assessed.

Marvel Team-Up #23, cover-dated July 1974, pairs Spider-Man with John Jameson in his lupine Man-Wolf identity, continuing a subplot that had been building through the Amazing Spider-Man title. The issue was written by Len Wein with artwork by Gil Kane, both well-regarded Bronze Age craftsmen whose collaborations on Marvel's team-up and street-level titles are consistently reliable but not typically headline events. There is no first appearance, origin, or death recorded in this issue; it functions as a mid-run chapter in an ongoing supporting-cast storyline rather than a foundational Marvel Universe moment.

Market data reflects that secondary status: pricing across the certified grade spectrum is modest and gradual, with values climbing from the high-$20s at low grades to roughly $90 at 9.4 before a steep run-up to $200 at 9.6 and $500 at 9.8. The wide census population relative to the small number of 9.8 copies explains the sharp premium at the top end, a common pattern for Bronze Age Marvel back-up titles where high-grade survival is scarcer than raw supply would suggest. Demand is driven primarily by Spider-Man team-up completists and Man-Wolf character collectors rather than broad speculative interest.

This book trades as a solid but unspectacular mid-run Bronze Age title: affordable in low and mid grades for readers and run-builders, with real scarcity value only emerging at the 9.6-9.8 tier for census-chasers and registry participants. It is not a book that commands attention at auction on its own merits, but it remains a steady, liquid piece of any complete Marvel Team-Up or Spider-Man supporting-character collection.
