I'm currently reading issue #50 which is a full-color look at the Bronze Age adventures of Batman and I think I'll probably be pre-ordering #52, news of which just crossed my desk.
Here's a quick description from the publisher:
BACK ISSUE #52 (84 pages, FULL-COLOR, $8.95) spotlights Mystery Comics of the Bronze Age! All-new interviews with artists BERNIE WRIGHTSON, SERGIO ARAGONÉS, GERRY TALAOC, and DC mystery writer LORE SHOBERG—and MARK EVANIER and DAN SPIEGLE discuss Scooby-Doo (Zoinks!). Plus: DC’s Horror Hosts and Ghosts, Charlton Comics’ chiller anthologies, and damsels of darkness Black Orchid and Madame Xanadu. Featuring art and/or commentary by TONY DeZUNIGA, MICHAEL Wm. KALUTA, VAL MAYERIK, DAVID MICHELINIE, MATT WAGNER, and more, with a rarely seen House of Mystery painting by Wrightson as the cover! Now in FULL COLOR! Edited by MICHAEL EURY.Zoinks, indeed!
