ADVENTURE COMICS #350

Image is upside down; cover appears complete with bright, mostly unfaded color on the yellow and pink title band. Some visible surface wear and light creasing along the edges, with a possible small crease near the spine area and minor corner softness. There is slight waviness/warping to the cover suggesting handling or humidity exposure. Interior and back cover were not assessed, and the book is in a protective sleeve which slightly obscures fine surface detail.

Adventure Comics #350 arrived during the period when the Legion of Super-Heroes had fully supplanted Superboy as the headline feature of DC's long-running anthology title, reflecting the character group's rising popularity through the mid-1960s. Curt Swan's clean, classical linework anchored the book's visual identity during this stretch, with Jim Shooter's youthful but ambitious scripting driving the Legion's expanding 30th-century mythology forward. The issue sits within a run that, while not headlined by a single first appearance or origin story, is prized by Legion completists for its place in the ongoing team continuity of the era.

Market data shows a typical Silver Age back-issue value curve: modest pricing through mid grades, a pronounced climb above 9.0, and very thin supply at the top of the census. Demand is driven almost entirely by Legion of Super-Heroes and Silver Age DC anthology collectors rather than by any landmark first-appearance premium, since the issue's significance is contextual rather than definitional. Certified population data shows steady grading activity across the mid-range but only a single 9.8, underscoring how difficult true gem-mint survivors are to find for a print run of this vintage.

This issue trades as a solid but unspectacular mid-run Silver Age DC book. Lower and mid-grade raw copies move steadily among run-builders and Legion specialists at modest prices, while high-grade certified copies command outsized premiums driven almost entirely by scarcity rather than character or story significance. Collectors assembling a complete Legion of Super-Heroes or Adventure Comics run represent the primary buyer base, with speculative interest limited given the absence of a recognized key moment in this specific issue.
