So I mentioned this before in my only other post, but I just now received it, so I thought I'd show it off. I bought this from Roger Epperson's site. It is signed by David Byron, Gary Thain, Ken Hensley, Lee Kerslake, and Mick Box. Unfortunately it's a bit annoying to pick out the signatures due to black on black, as well as that Gary Thain's signature and Lee Kerslake's signature got mixed together a bit, and Lee and Lee's signatures are upside down. It took a bit of analyzing to clearly locate where they were.
David Byron: Center Upper, clearest one.
Mick Box: Right next to Byron
Ken Hensley: Upside down below Byron and Box
Gary Thain: To the right bottom corner
Lee Kerslake: Almost impossible to see clearly at this angle, but it's upside down right below Thain's.
