MARVEL TWO-IN-ONE #23

Cover shows strong gloss and vivid color with sharp corners; a light vertical crease is visible near the spine at upper left, and there is minor rubbing at the top edge. Slight glare from a protective sleeve obscures fine surface detail. No major creases, tears, or color-breaking spine stress are evident from this angle. Interior pages and back cover were not assessed.

Marvel Two-In-One #23 pairs Ben Grimm, the Thing, with Thor for a story rooted in Egyptian mythology, bringing in Horus, Isis, Osiris, and the god of chaos Seth as the antagonist Mysterium manipulates their power. The issue was written by Bill Mantlo, with plotting input from Jim Shooter, and drawn by Marie Severin with inks split between Joe Sinnott and Pablo Marcos; Archie Goodwin edited. It falls in the early-to-middle stretch of the Two-In-One series, which built its identity on rotating guest stars alongside the Thing rather than any single recurring villain or arc, and this issue is representative of that format rather than a departure from it.

As a Bronze Age team-up book without a first appearance, major creator landmark, or storyline widely cited in price guides, the issue sits in the bulk-stock tier of the market. Demand is driven mainly by completists assembling a full run of Marvel Two-In-One or by Thor and Thing crossover collectors rather than by any character-origin or key-cover interest. The Egyptian-mythology guest cast gives the issue some thematic novelty within the series but has not translated into elevated demand relative to other issues from the same stretch.

Copies of this issue circulate readily in reader and mid grades through back-issue bins, online lot sales, and dealer inventory, and pricing stays close to cover price outside of certified high grade. Certified 9.8 copies are scarce simply because so few were preserved and submitted, which supports a modest premium at the top of the grade scale even though the book has no independent key status. Buyers are typically series runners and Thing or Thor team-up collectors rather than investment-driven purchasers, and the book should be expected to trade as a common, steadily available title across most grades.
