I would appreciate the community's feedback on the possible authenticity of the shown signatures on the backside of a copy of Lynyrd Skynyrd's Second Helping LP. The signatures that I can verify are Billy Powell (piano), Gary Rossington (guitar), Allen Collins (guitar), Ed King (guitar) and Leon Wilkeson (bass). The signature to the left of Ed King's photo may be Ronnie Van Zant, but I am not going to hold my breathe on that one until I get some additional feedback from the community.  Some of these look similar to other examples I have seen, but a couple I am not sure of. I appreciate feedback from those familiar w/ the band's signatures.
