After years of putting out Comic Buyers Guide the newsprint magazine, CBG launched a price guide to compete with Wizard Magazine. Check out this scan of Comic Buyers Guide Price Guide #28 which features a Chaos Effect cover by Bob Layton and several interesting Valiant articles.
The art is from one of the Chaos Effect promo cards. Characters on the cover include X-O Manowar, Armorines, Spider Aliens and the H.A.R.D. Corps.
