MARVEL TWO-IN-ONE #13

Cover shows strong gloss and bright color with sharp corners and clean edges; only minor handling wear is visible at the corner tips and a faint vertical crease line may be present near the spine. No major creases, tears, or color breaks are evident in this photo, and the book appears to be in a protective sleeve. Interior pages and back cover were not assessed, so the grade is based solely on the visible front cover.

Marvel Two-In-One launched in 1974 as a rotating team-up vehicle for Ben Grimm, the Thing, following the model of DC's The Brave and the Bold and Marvel's own Marvel Team-Up. By early 1976, when issue #13 was released, the title had settled into a regular creative rhythm under writer Bill Mantlo with pencils typically supplied by Sal Buscema, pairing the ever-lovin' blue-eyed Thing with a different corner of the Marvel Universe each month. The series holds a secure if unglamorous place in Bronze Age continuity, functioning as connective tissue between the Fantastic Four's adventures and the wider Marvel line rather than as a showcase for any single landmark event.

The market for this issue reflects its status as a solid mid-run entry in a well-collected but non-key series: certified population is moderate, sales activity is present but thin at the top end, and pricing climbs steeply only in the 9.4-9.8 range, consistent with a book valued primarily for condition rarity rather than content-driven demand. The gap between the last hard sales data point and the 9.8 FMV, along with a materially higher one-year average than the current fair market value, suggests a book that saw a brief run-up in collector or investor interest before settling back toward its structural baseline.

This is a title for series completists, Thing/Fantastic Four collectors, and Bronze Age dealers building out full runs rather than for buyers chasing a marquee key. Lower and mid-grade raw copies trade cheaply and steadily as reading or filler copies for long boxes and want lists, while pristine CGC 9.8 slabs command a real premium purely on eye appeal and scarcity at the top of the census. Expect this issue to move briskly at low price points and to find a smaller, patient pool of buyers for top-graded submissions.
