Mark Huesman joined Geppi's Entertainment Publishing & Auctions' staff in 1997 as the Pricing Coordinator, a position that metamorphosized into a Production Coordinator position in 2003. A lifelong resident of Baltimore, born on the calendar day with the highest consonant- to-vowel ratio, Mark’s fascination with comics started as a 4-year old following the adventures of Batman from Adam West to those books with cool drawings and indecipherable words. Then Mark learned to read…  And now almost overnight, and 37-some years later, Mark works at the very heart of the collectables industry, nurturing the growth and development of the computer layout files that bloom into some of Gemstone’s many fine publications

Gemstone Publishing - Missouri Office

For the past 30 years Russ Cochran has been collecting and publishing comic art. Russ Cochran was born in West Plains, Missouri. Without television in the 1940s, Russ developed a passion for comic books. In 1964 Russ earned his Ph.D. in Physics and became the Chairman of the Drake University Physics Department in Des Moines, Iowa. As time passed, Russ felt the  desire to become a collector of the comic books he had always enjoyed in his youth. The hobby brought him to his first comic book convention in 1965. Russ pursued a collector’s connection with Bill Gaines, publisher of EC Comics and MAD Magazine. Bill Gaines and Russ Cochran shared a mutual enthusiasm which led to a great friendship. Their relationship inspired Russ Cochran to republish the entire collection of EC comics. In 1975 Russ followed his dream by moving back to West Plains, Missouri while devoting all of his energy toward publishing. Today Russ Cochran’s Auction offers select comic art for those collectors who share his appreciation and nostalgia. More About Russ
