Here's an update on my 3 multi-sig books plus a 4th:
Batman #700
Most of these sigs were on it when I bought the book. I had Tony Daniel, Frank Quitely and Bill Sienkiewicz added at Wondercon
Batman #400
My original owner copy. I had Mike Grell, George Perez and Art Adams added at Pitt and BCC. And it kept the 9.8
Heroes Against Hunger
My original owner copy. I had Marv Wolfman, Len Wein and Bill Sienkiewicz added at Wondercon. It too held onto the 9.8
Heroes for Hope #1
My original owner copy. I had Joe Sinnott, Art Adams, Jim Starlin and Howard Chaykin added at Pitt and BCC. The good news is it's an 8.5, so I'm not terribly concerned about condition. The bad news is...well, it's an 8.5
