with Dark Horse, DC Comics, Image Comics, and IDW Publishing taking precedence as "Premier" publishers. Marvel Comics has its own mini-catalog of Marvel Previews available separately, for contractual reasons. Geppi is also owner of Gemstone Publishing Inc., through which he publishes The Overstreet Comic Book Price Guide. Gemstone has also published Russ Cochran's EC Comics reprints, Disney comics and Blue Book price guide in the past as well. Baltimore In 1994, Geppi purchased Baltimore magazine, "a 50,000 circulation monthly and one of the nation's oldest regional publications." Gemstone Publishing Geppi's publishing ventures in the comics field saw him create Gemstone Publishing Inc., which was formed in large part from other purchases. In 1992, Diamond bought Ernst Gerber Publishing (publisher-author of the Photo-Journal Guide to Comics). E. Gerber Products, LLC is a Diamond-affiliated company started by Gerber in 1977 which sells Mylar bags as well as "acid-free boxes and acid-free backing boards" for comics collectors to store their collection in.

Long-term EC Comics fan Cochran auctioned Bill Gaines' personal file copies of EC publications, as well as most pages of original EC artwork (which, almost uniquely, Gaines had maintained ownership and possession of), before being granted the reprint rights to the EC back catalog itself. Geppi included Cochran's publications — and Cochran himself — under his new imprint, Gemstone Publishing.

Many Gemstone publications revolve around Comic Book Marketplace-editor and EC-shepherd Russ Cochran. EC Comics reprints Cochran, like Geppi, was a particular fan of Carl Barks' Disney comics, and had previously-published EC reprints in association with Disney-reprinter Gladstone Publishing. In the early 1990s, Geppi's Gemstone embarked on a full series of reprints of classic EC titles, starting with new reprints of the Cochran/Gladstone-reprints of The Haunt of Fear, The Vault of Horror and Weird Science (all 1992). Gemstone also republished (in single issue and 'annual' — four issues per 'annual' — format) EC's New Trend and New Direction titles (with the exception of Mad) between 1992 and 2000. In 2005, Gemstone
