In 1954, industry legends Joe Simon and Jack Kirby founded Mainline Publications to publish their own comics during that turbulent era in comics history. The four titles--Bullseye, Foxhole, Police Trap, and In Love--looked to build off their reputation as hit makers in the Western, War, Crime, and Romance genres, but the 1950s backlash against comics killed any chance at success, and Mainline closed its doors just two years later. For the first time, TwoMorrows Publishing is compiling the best of Simon & Kirby's Mainline comics work, including all of the stories with S&K art, as well as key tales with contributions by Mort Meskin and others. After the company's dissolution, their partnership ended with Simon leaving comics for advertising, and Kirby taking unused Mainline concepts to both DC and Marvel. This collection bridges the gap between Simon & Kirby's peak with their 1950s romance comics, and the lows that led to Kirby's resurgence with Challengers of the Unknown and the early Marvel Universe. With loving art restoration by Chris Fama, and an historical overview by John Morrow to put it all into perspective, the Best of Simon & Kirby's Mainline Comics presents some of the final, and finest, work Joe and Jack ever produced!
