In addition to contributing to the Art of Modern Rock series, King has also written for Juxtapoz, interviewing poster artist Derek Hess, and about Japanese pop culture memorabilia for The Antiquer. In 1991, he wrote for and published Japanese Baseball Card Quarterly. He published the first and only issue of The Rock Poster Collector, an attempt to promote and provide a resource for collecting rock posters and which included an article by John Lyons. This attempt to organize the collecting community was followed soon after by the creation of The Rock Poster Society (TRPS).
