TALES TO ASTONISH #27

This key Silver Age issue (first appearance of Henry Pym) shows notable wear: a diagonal crease/tear running through the upper masthead area, soiling and discoloration especially along the top edge, and general handling wear with rounded/softened corners. There's a spine stress area visible near the top and some surface scuffing across the cover art. The book is in a protective sleeve which limits full assessment; interior pages and back cover were not visible for evaluation.

Tales to Astonish #27 is an Atlas/Marvel science-fiction anthology issue built around "The Man in the Ant Hill," the Stan Lee and Larry Lieber story with art by Jack Kirby and Dick Ayers that introduces scientist Henry Pym. Pym does not yet wear a costume or carry the Ant-Man name here, but the shrinking formula and premise established in this story are directly recycled when Marvel launches the Ant-Man feature in Tales to Astonish #35 the following year, making this issue the acknowledged conceptual first appearance of the character. It arrives at the tail end of Atlas's giant-monster and sci-fi anthology era, just as the same creative team was pivoting the line toward the costumed-hero format that would define the Marvel Age.

Market data shows a steep, non-linear climb in value once a copy clears the mid-grade range, consistent with a book that was not saved in quantity and is scarce above 8.0. Demand is driven almost entirely by the Pym/Ant-Man connection rather than by the anthology's other contents, and the Kirby cover adds secondary appeal among Atlas-era cover collectors. With over a thousand copies graded but only a handful above 9.0 and none certified at 9.8, high-grade examples are genuinely rare relative to demand, which explains the disproportionate premium paid for the best-known copies compared to the broader curve.

The book is bought across two overlapping audiences: Marvel key-issue collectors building an Ant-Man/Avengers-adjacent run, and Atlas/Silver Age specialists focused on Kirby cover work and pre-hero Marvel science fiction. Lower and mid-grade copies trade steadily as accessible ways to own the character's origin point, while the small handful of copies in the 8.5-and-up range are effectively singular market events whenever they surface, with pricing set less by a smooth grade curve than by whatever the last comparable top-census sale established.
