CREATURES ON THE LOOSE #16

Cover shows a vertical crease running through the left side and spine area, along with some minor surface wear and light waviness/warping across the cover consistent with age. Corners appear reasonably sharp with only slight blunting, and colors remain bright with no notable fading. The book is protected in a plastic sleeve, which obscures fine detail assessment; interior and back cover were not examined.

Creatures on the Loose #16 (March 1972) marked Marvel's entry into sword-and-planet adventure fiction predating the company's later Warlord of Mars and John Carter licensing efforts. The issue adapted Edwin Lester Arnold's 1905 novel Lieutenant Gullivar Jones: His Vacation, with a script by Gardner Fox, a veteran writer known for his work on the Justice Society and countless Golden and Silver Age features, and artwork by Gray Morrow, whose polished, illustrative style suited the pulp-adventure tone. This adaptation introduced Marvel's version of Gullivar Jones to its line, running as a backup feature through several subsequent issues of the anthology title.

Market data reflects a book with limited but steady collector interest rather than broad demand. Certified population is modest at just over sixty copies, and sales activity across most grades is sparse, typically one to a handful of transactions per grade tier. Pricing rises gradually through the mid grades before climbing more sharply at the top of the census, a pattern typical of Bronze Age anthology titles that survive in decent supply but see little competition for high-grade examples. The absence of any 10.0 or 9.9 certified copies, paired with only a handful of 9.8s, suggests the ceiling is set by a small, dedicated pool of buyers rather than sustained bidding pressure.

This is a book for specialists in sword-and-planet fiction, Gardner Fox completists, and Bronze Age anthology collectors rather than mainstream superhero buyers. Raw copies in worn condition trade cheaply and are readily available, while mid-grade examples remain affordable entry points for readers assembling a run of the series. High-grade certified copies, particularly 9.6 and 9.8, command a real premium reflecting their scarcity on census, and are the primary target for collectors seeking a top-tier example of this early Marvel foray into planetary romance.
