JOHN CARTER, WARLORD OF MARS #18

Cover shows strong gloss and vibrant color with sharp corners and a clean spine with no visible ticks or stress lines. There is a small edge nick along the left border and minor handling wear at the top left corner. The book is protected in a plastic sleeve, which limits full assessment of surface sheen and back cover condition; interior pages were not visible for review.

John Carter, Warlord of Mars #18 adapts Edgar Rice Burroughs' Barsoom mythos through the lens of two artists who would soon reshape mainstream comics. Chris Claremont scripts the issue, bringing John Carter, Dejah Thoris, Tars Tarkas, Tardos Mors, and Kantos Kan through another chapter of Martian political intrigue, but the issue's lasting draw is craft rather than continuity: Frank Miller pencils, inked by Bob McLeod, in one of his first professional assignments for Marvel, months before his star-making run on Daredevil beginning with #158 would establish him as one of the defining artists of the era. John Byrne, already ascending through his own X-Men and Marvel Team-Up work, supplies the cover. No character makes a first appearance here, and the issue is not typically cited as a cover classic in price guides.

Market data reflects a book valued primarily for its creator pedigree rather than any landmark story event. Certified population is substantial for a lower-circulation licensed title, with over 200 total graded copies and steady turnover across the grade spectrum, indicating an active collector base tracking early Miller material specifically. The FMV curve shows a pronounced premium jump at the top end, with 9.8 copies commanding several multiples of the 9.4-9.6 range, consistent with a book where high-grade survivors are scarce relative to demand from Miller completists and Bronze Age Marvel specialists. Mid- and low-grade copies trade closer to commodity pricing for the series, since the appeal for those buyers is reading and reference rather than investment-grade preservation.},{
