And, of course, it comes with new market reports, updated prices, and much more! The Bible of serious comic book collectors, dealers, and historians since it was first published in 1970, the Guide is released each July by Gemstone Publishing. Compiled by founder Robert M. Overstreet with contributions from an extensive roster of Overstreet Advisors, the Guide offers insight into the complex and exciting comic book market. Cover by TMNT co-creator Kevin Eastman.
