SUPER-VILLAIN TEAM-UP #13

Cover shows strong gloss and vivid color with sharp corners and no visible creases or tears. There is minor edge wear at the top and bottom spine areas and a very slight softness at the upper right corner. The book is in a protective sleeve, which obscures fine detail assessment of the surface, and interior pages and back cover were not visible for review.

Super-Villain Team-Up #13 caps the Namor co-starring run of the series, pitting Doctor Doom and the Sub-Mariner against the subterranean tyrant Krang amid the sunken ruins of Atlantis. Scripted by Bill Mantlo with pencils by a young Keith Giffen and a Frank Giacoia cover, the issue sits within a lesser-chronicled corner of Marvel's Bronze Age villain-team experiments, offering readers of the era a rare full-length showcase for Doom operating outside his usual Fantastic Four orbit.

Market data shows a typical long-tail Bronze Age curve: values stay flat and modest through the mid grades before climbing sharply near the top of the census, with CGC 9.8 copies commanding roughly ten times the price of a 9.0. Demand is driven almost entirely by Doctor Doom and Namor completists and by Bronze Age Marvel villain-team runs rather than by any first appearance or landmark event in this specific issue, keeping raw and mid-grade copies inexpensive and largely overlooked outside dedicated series collectors.

This is a book bought mainly by Doom and Namor character collectors filling out Super-Villain Team-Up runs, plus a small pool of Giffen-art completists drawn to his early pencils. Raw copies in low and mid grades move slowly and cheaply as reading or filler copies, while the handful of high-grade CGC 9.8 slabs attract steady, if infrequent, competition given the low census population at the top of the pyramid.
