As I'm unemployed right now, I'm selling some items from my collection on RR Auctions... Take a look on this one:

Item #766 -  Beatles: John Lennon

Description

Choice glossy 8 x 10 photo from the cover of Lennon’s Rock 'n' Roll album, signed at the bottom in black felt tip. In fine condition. Accompanied by a letter of authenticity from noted Beatles expert Frank Caiazzo, in which he writes, “The signature on this photo dates from the mid-1970’s, and it is an excellent example from the period.” A highly desirable photo in simply stunning condition.
