ADVENTURE COMICS #290

This Silver Age 10-cent issue shows significant handling wear: heavy spine stress with multiple ticks and a vertical crease running through the upper spine area, rounded and worn corners, and noticeable edge chipping along the top and right edges. There is visible surface loss/scuffing in the upper right and lower right corners, a diagonal crease across the lower right cover area, and general wear/soiling to the cover surface consistent with age. The interior and back cover were not visible in this photo and were not assessed.

Adventure Comics #290 lands in the fertile early-1960s stretch when the title was anchored by Superboy solo adventures while National (DC) steadily wove the Legion of Super-Heroes into its pages, building toward the feature's permanent residency later in the run. Cover-dated November 1961, the book sits within the celebrated Weisinger-office Superman family of titles, the editorial engine that generated much of the era's most collected DC material. It represents the house style of the period: clean, imaginative science-fiction premises rendered by the studio's core creative talent.

The market profile is that of a solid, mid-tier Silver Age DC issue rather than a headline key. Certified copies are reasonably plentiful through the mid grades, with prices holding steady in the low double digits from Very Good through Fine and climbing meaningfully only as copies approach the top of the census. High-grade examples are genuinely scarce: the census thins dramatically above 9.0, and no 9.8 has yet been certified, which concentrates collector competition on the handful of 9.0-to-9.2 survivors and supports a strong premium at the apex.

Demand comes primarily from Adventure Comics run collectors and Legion/Superboy completists assembling the pre-#300 stretch, along with buyers seeking clean, well-centered Silver Age DC in investment grade. Across the middle of the market the book trades affordably and predictably, making it accessible reading-copy and set-filler territory; the action shifts sharply at the top, where the absence of high-census slabs means any 9.4-and-up example commands attention well beyond the mid-grade curve.
