IRON MAN #129

Cover shows strong gloss and vibrant color with sharp corners and no visible creases or color breaks. Slight edge wear is visible along the top and right border, and minor spine stress cannot be fully assessed due to the comic being encased in a protective sleeve. No stains, tears, or writing are visible on the front cover. Interior pages and back cover were not assessed.

Iron Man #129 arrived in December 1979 as the direct aftermath issue to the celebrated "Demon in a Bottle" arc, the David Michelinie, Bob Layton, and John Romita Jr. run that confronted Tony Stark's alcoholism and reshaped the character's interior life for the rest of the Bronze Age. While the storyline's most iconic single issue remains its immediate predecessor, #129 continues the fallout for Stark and his supporting cast, including Bethany Cabe, and reflects the same creative team's efforts to bring a grounded, adult sensibility to the Armored Avenger during a period when Marvel was experimenting with sustained character drama inside a superhero framework.

Market activity for the issue is thin, with certified sales data limited to single digits across the graded population. Demand is concentrated almost entirely at the top of the grade scale, where nine-point-eight copies command a real premium over anything in the 9.4-9.6 range, a pattern typical of common late-1970s newsstand Marvel titles that were not routinely preserved in high grade. Below that tier, values compress quickly, and raw copies in low and mid grade trade closer to bulk-book pricing than to storyline-driven premiums.

The book appeals mainly to Iron Man completists and readers assembling the full "Demon in a Bottle" run rather than to speculators chasing a first appearance or a singular key moment. Mid- and low-grade raw copies are readily available and inexpensive, suited to reading copies or run-fillers, while the CGC 9.8 tier is the only segment where meaningful bidding competition and scarcity currently drive price.
