IRON MAN #36

Cover shows moderate wear typical of a Bronze Age book: light spine stress with faint ticks visible along the spine edge, mild corner softening at top and bottom corners, and slight surface wear/rubbing to the ink especially near the edges. No major creases, tears, or color breaks are evident, and the cover retains good color gloss overall. The book is in a protective sleeve, which limits full assessment of edges; back cover and interior pages were not visible and were not assessed.

The Invincible Iron Man #36 (April 1971) arrived during the George Tuska/Johnny Craig art run that defined the title's early Bronze Age look, with a script credited to Allyn Brodsky. The issue is best known among back-issue specialists as the first appearance of Firebrand, in his original identity of Gary Gilbert, a recurring foe who would later resurface in altered forms across Iron Man's rogues' gallery. As a villain-origin issue from a non-blockbuster stretch of the series, it occupies a modest but genuine niche in the character-first-appearance collecting hierarchy rather than the marquee tier of Iron Man keys.

Market data shows a book that is plentiful in the mid grades and thins out sharply above 9.4, with 189 of 196 certified copies concentrated well below the top of the census. Price appreciation across the CGC curve is gradual through the mid-grade range and accelerates only near 9.6, consistent with a Bronze Age title whose demand is driven by completists of the Iron Man run and by Firebrand-specific character collectors rather than broad mainstream interest. The complete absence of a certified 9.8 despite sixteen census copies at that unconfirmed tier and six recorded high-end sales points to a genuine ceiling rarity that has not yet been priced by a landmark sale.

This is a book that trades quietly: raw copies in low and mid grades move steadily through online marketplaces and back-issue bins as filler for Iron Man run collections, while high-grade certified examples appeal to a narrower band of character-first-appearance and Bronze Age superhero-villain specialists. Buyers seeking this title are typically assembling a complete Iron Man volume 1 run or targeting Firebrand's publication history specifically; it is not a book driven by broad speculative demand, and pricing across grades should be expected to track incrementally with census population rather than spike on renewed character exposure.
