Mainline was a very short-lived company started by Jack Kirby and Joe Simon in an attempt to publish their own material. Distribution issues led to its demise (ain't that always the case?), but not before they left behind a number of interesting books. One that has always intrigued me is Foxhole, as it was an attempt to bring more realism to the war genre with stories written and drawn by veterans. Kirby saw a lot of violence during his time in the service, and I'm sure he felt that comic book readers would appreciate stories with a bit more gravitas. Four issues were published by Mainline, and the title was sold to Charlton. The 5th and 6th issues features Mainline inventory but I believe that the 7th and final issue was new material assembled in Derby. Some Foxhole stories appeared in the early 80s in Charlton's Battlefield Action title, but I truly think that it is high time someone put together a nice volume reprinting this tough to find (and harder to afford) material.
