MARVEL TEAM-UP #139

Cover shows strong gloss and vibrant, unfaded color with sharp, square corners and no visible spine stress lines or ticks. No creases, tears, or stains are apparent, and the image is crisp with minimal print/registration issues typical of the era. Book is housed in a protective sleeve which limits ability to check edges closely for micro-chipping; interior pages and back cover were not assessed.

Marvel Team-Up #139 (March 1984) pairs Spider-Man with the shadow-wielding vigilantes Cloak and Dagger, characters introduced two years earlier in Peter Parker, The Spectacular Spider-Man #64. Written by J.M. DeMatteis with art by Greg LaRocque, the issue continues the title's long tradition of rotating guest stars alongside Spider-Man and reflects Marvel's early-1980s push to expand its street-level, socially conscious corner of the shared universe through emerging characters like Cloak and Dagger.

The book's market profile is characteristic of a mid-run Copper Age direct-market title: abundant high-grade survivors, a steep FMV drop-off below near-mint condition, and modest demand outside of completists and Cloak and Dagger collectors. The certified population is heavily weighted toward 9.6 and 9.8, with sales data thinning dramatically below 9.0, indicating that most collector interest is concentrated at the top of the grade scale rather than across the run.

This issue trades primarily as a bulk or want-list book rather than a marquee key, appealing to Spider-Man team-up runs, Cloak and Dagger character collectors, and CGC 9.8 registry builders chasing complete Marvel Team-Up sets. Raw copies in low and mid grades carry minimal premium and are readily available, while the 9.8 slab commands the bulk of the book's value, reflecting a typical Copper Age price curve rather than any landmark first-appearance status.
