ADVENTURE COMICS #353

This 1967 issue predates the direct/newsstand distinction so no variant applies. Visible defects include noticeable spine wear with stress lines and a small tear/split at the top of the spine, moderate corner softening particularly at top corners, and general surface wear with a slightly muted/dulled cover gloss consistent with handling. There is also some minor edge wear along the top edge. The book is in a protective sleeve; interior pages and back cover were not assessed.

Adventure Comics #353 (February 1967) is best remembered among Legion of Super-Heroes collectors as the first appearance of Computo, the rogue robot antagonist introduced in "Computo, the Conqueror!" The story was scripted by teenage prodigy Jim Shooter during his celebrated early run on the Legion feature, with art by Curt Swan and George Klein, and the issue also carries a Supergirl backup story typical of Adventure's mid-1960s format, when the Maid of Steel co-headlined the title alongside the Legion's adventures in the far future.

The book's market profile reflects a lightly collected Silver Age DC title rather than a mainstream key: certified population is modest (59 CGC Universal copies within a total graded count of 77), and sales activity is thin at every grade tier, with only a handful of transactions recorded above 8.0. Values rise steadily but not dramatically through the mid grades, then climb more sharply above 9.0, where census population thins out and no 9.6 or 9.8 sales have yet been recorded, suggesting real scarcity premiums would apply at the very top of the grading scale.

Demand centers on Legion of Super-Heroes completists and Jim Shooter-era specialists rather than broad mainstream key-issue buyers, which keeps raw low- and mid-grade copies affordable and readily available. High-grade certified copies, by contrast, are genuinely scarce given the small surviving population at 9.0 and above, so a well-preserved 9.8 would likely draw strong competitive bidding among Legion and Silver Age DC specialists despite the book's second-tier status relative to major universe-defining first appearances.
