JOHN CARTER, WARLORD OF MARS #17

Cover shows strong gloss and vibrant color with sharp corners; no visible creases or color breaks in this photo. There is a faint horizontal handling mark near the lower right corner and slight waviness along the top edge, likely from the protective sleeve rather than the book itself. Barcode box present confirms newsstand edition. Interior and back cover were not assessed, so grade is based solely on the visible front cover.

John Carter, Warlord of Mars #17 is a Bronze Age adaptation-adjacent adventure title from Marvel's late-1970s line, adapting the Edgar Rice Burroughs Barsoom mythos with a script by Chris Claremont, art by Ernie Colon and Bob Layton, and a Gil Kane cover. The series occupies a niche corner of Marvel's licensed-property output of the era, sitting alongside other sword-and-planet and pulp adaptations that populated newsstands but never achieved the sales or cultural traction of Marvel's core superhero line. No first appearances, deaths, or landmark creative firsts are attached to this specific issue; its interest is rooted in Claremont's presence as writer during his early rise and in the Kane cover art rather than any content milestone.

The certified population is small, with only thirteen total graded copies and eleven in the CGC Universal census, reflecting minimal collector demand and correspondingly thin submission activity. Recorded FMV data clusters narrowly in the mid-$20s range across grades 8 through 9.6, suggesting the book trades as a bulk Bronze Age filler title rather than a demand-driven collectible, with grade making only marginal difference in price outside the top end of the census. The single 9.8 on record has no associated sale price, and the overall sales count across all grades remains low, limiting the reliability of any curve beyond broad strokes.

This issue suits completists assembling a full run of Marvel's John Carter series, Claremont bibliography collectors, or admirers of Gil Kane cover work rather than speculative buyers. Raw copies in low and mid grade should remain inexpensive and easy to source, while a Universal 9.8 will command a premium chiefly due to census scarcity rather than any documented sales record at that grade. Expect slow, low-volume trading across all grades with limited upward pressure absent a broader resurgence of interest in Marvel's Burroughs adaptations.
