ADVENTURE COMICS #358

Cover shows good color and gloss with sharp corners, but there is visible surface waviness/rippling across the black background suggesting slight moisture exposure or handling stress, and a faint vertical crease near the left edge. Slight wear is visible at the top and bottom spine edges with minor rubbing at the corners. The book is protected in a plastic sleeve which obscures some fine detail; interior and back cover were not assessed.

Adventure Comics #358 arrived in mid-1967 during the run when the Legion of Super-Heroes had taken over the anthology title as its primary feature, a period marked by the remarkably young Jim Shooter scripting alongside Curt Swan's clean, dynamic pencils. The issue is representative of the era's 30th-century adventure formula: tightly plotted team stories built around the Legion's rotating roster of super-powered teenagers, blending science-fiction concepts with the moral clarity typical of DC's house style before the medium's tonal shift later in the decade. It carries no first appearance or origin story of lasting significance, but it stands as a good example of the Shooter/Swan Legion collaborations that are still studied and referenced by fans of the feature's classic period.

Market data for this issue is thin, with certified sales scattered across a thirty-book census and long gaps between recorded transactions in the mid grades. Pricing is essentially flat from grade 3.0 through 6.0, all clustering near eighty dollars, which reflects steady but unspectacular collector interest rather than active bidding competition. Values begin to separate meaningfully only at 9.2 and above, where a small pool of highly preserved copies pulls stronger prices, and the jump from 9.4 to 9.6 shows the kind of grade-sensitive premium typical of Silver Age back-up features once the pool of pristine copies narrows sharply.

This is a book for Legion of Super-Heroes completists and Silver Age DC readers building out the Adventure Comics run rather than a speculative or investment-grade key. Lower and mid-grade raw copies will move steadily but modestly, priced for readers rather than investors, while the rare high-grade certified copy commands a real premium given the extreme scarcity above 9.4. With only a single 9.8 recorded and no sales data at that grade, a top-graded copy would likely draw strong competitive bidding from census-completion buyers rather than general Legion collectors.
