FANTASTIC FOUR #43

Cover shows notable wear consistent with a mid-grade Silver Age book: heavy spine stress with multiple ticks and a visible spine split/tear at the top edge, corner rounding and slight blunting at all four corners, and general surface wear with some color rubbing along the spine. There is minor foxing/discoloration in the cover stock and a small crease near the top right corner. Book is in a protective sleeve which creates glare, obscuring finer surface detail; back cover and interior pages were not assessed.

Fantastic Four #43 (October 1965) closes the three-part Frightful Four arc that began in issue #41, with Stan Lee scripting and Jack Kirby on pencils, inked by Vince Colletta. The story pits the team against the Frightful Four (Medusa, Sandman, Wizard, and Trapster) in a battle centered on the Baxter Building, capping a run widely regarded as one of the strongest sustained storylines of the early Lee-Kirby Fantastic Four. While it introduces no new characters or origins, the issue is valued by Silver Age collectors as a satisfying middle-run chapter from Marvel's flagship title during its creative peak.

Market data shows a typical Silver Age demand curve: values stay compressed and flat across low-to-mid grades (roughly $30-$100 from grade 2.0 through 7.5), reflecting a large surviving population of well-read copies, then rise sharply from 9.0 upward as census population thins dramatically. With only three 9.8 copies certified against 549 total Universal-graded copies, the top grade commands a steep premium, evidenced by recent sales in the $5,500 range. This shape is consistent with non-key Silver Age Marvel issues that trade on completism and Kirby art rather than first-appearance demand.

The book primarily appeals to Fantastic Four run collectors and Silver Age Marvel completists assembling the full Lee-Kirby stretch rather than speculators chasing a single defining moment. Lower and mid-grade raw copies move steadily but modestly as affordable reading or filler copies, while pristine 9.6-9.8 slabs are scarce enough to draw competitive bidding whenever they surface, given the thin population at the top of the census.
