Just got this news from TwoMorrows Publishing. It looks like
Back Issue #20 has some good Superman-related content:
BACK ISSUE 20
Now with COLOR! In Back Issue 20, peek behind the masks of many of your favorite heroes in this Secret Identities issue, as we explore the histories of four characters with unusual alter egos: Firestorm, Moon Knight, the Question, and the "real-life" super-hero the Human Fly! STEVE ENGLEHART and SAL BUSCEMA talk "Pro2Pro" about their Captain America collaboration, and JERRY ORDWAY is spotlighted in a career-spanning interview.
Plus: a roundtable of Superman writers and artists reveal the scoop on Clark Kent, featuring artwork by and commentary from BILL SIENKIEWICZ, KEVIN NOWLAN, DOUG MOENCH, DENYS COWAN, DENNY O’NEIL, AL MILGROM, GERRY CONWAY, FRANK ROBBINS, CARY BATES, ELLIOT S! MAGGIN, PAT BRODERICK, JIM SHOOTER, and many others.
BONUS: a Superman and Clark Kent COLOR art gallery, with ultra-rare art by CURT SWAN and others, and a Shazam! cover by Ordway, re-creating the classic "Spider-Man No More" cover from Amazing Spider-Man #50! Edited by MICHAEL EURY.
The 104 page with color section and cover, saddle-stitched 8 1/2" x 11" magazine with a full color cover and black-and-white interiors retails for $6.95 in the U.S. and ships 17 January 2007.
