ASTONISHING TALES #25

Cover shows strong gloss and bright colors with sharp corners and no visible creases or color breaks. There is minor edge wear along the top and right border and slight spine stress at the bottom, but no ticks or splits visible. The book is housed in a protective sleeve, obscuring fine surface detail; interior and back cover were not assessed. This cover date is pre-1977 so no direct/newsstand distinction applies.

Astonishing Tales #25 (Marvel, August 1974) marks the first appearance of Deathlok, the cyborg soldier Luther Manning, created by writer Doug Moench and artist/co-plotter Rich Buckler. The character's debut here displaced the long-running Ka-Zar feature that had anchored the anthology title, and its grim, dystopian tone-part man, part machine, fighting for survival in a ruined future America-stood apart from Marvel's costumed-hero mainstream and helped push mainstream comics toward harder science fiction and body-horror themes later in the decade. Deathlok went on to a long career across multiple Marvel series and media adaptations, cementing this issue's status as a foundational first appearance.

The book trades as a well-established Bronze Age key with deep, consistent sales data across nearly every grade on a census exceeding 3,400 copies. Demand is strongest at the top of the grade scale, where 9.8 copies command a substantial premium over 9.6 and below, reflecting both the character's durable fan base and the scarcity of pristine surviving copies from a period of lower-quality newsstand paper and handling. Mid- and low-grade copies remain comparatively affordable and see steady turnover, indicating a broad collector base rather than speculative spikes.

The issue appeals to Bronze Age key-issue collectors, Marvel character-origin specialists, and Deathlok completists tracking the character across his later solo runs and team-up appearances. Entry-level and reading copies are widely available and inexpensive, making this an accessible key for newer collectors, while high-grade CGC 9.8 examples are pursued more selectively by grade-focused investors given the sharp value gap at the top of the census.
