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 continues the anthology-style team-up format that paired the Thing with a rotating cast of Marvel heroes, here bringing in Thor for a story steeped in Egyptian mythology featuring Horus, Isis, Osiris, and Seth alongside the villain Mysterium. The issue reflects the era's fascination with mythological crossovers within the Marvel Universe, a trend also seen in contemporaneous Thor storylines. Scripting duties were shared by Bill Mantlo and Jim Shooter, with Marie Severin on pencils and a two-inker finish from Joe Sinnott and Pablo Marcos, giving the book a polished if unremarkable Bronze Age visual identity typical of the period's back-half Marvel output.

The market for this issue is modest and consistent with its status as a non-key, mid-run title. Sales activity clusters at the higher end of the certified population, with the majority of the 36 census copies falling in the 9.4-9.6 range, suggesting collectors have preserved this issue primarily in strong grades rather than reading copies entering the market. The absence of any sales data in low and mid raw grades indicates thin demand outside of high-grade certified copies, a common pattern for anthology-format team-up books that lack a first appearance or other historic hook.

This book appeals mainly to Marvel Two-In-One completists, Thing and Thor team-up collectors, and those building runs of the title rather than speculators chasing key issues. Raw copies in low and mid grade are readily available and inexpensive, reflecting minimal demand pressure, while the CGC 9.8 tier commands a substantial premium due to relative scarcity at the top of the census and steady interest from grade-chasing collectors. Overall, the issue trades as a stable but unspectacular piece of Bronze Age Marvel history, valued more for its place in a beloved team-up series than for any singular collectible significance.
