Signed by Joe Greene HOF, LC Greenwood Deceased 2013, Dwight White Deceased 2008, and Ernie Holmes Deceased 2008. Normally we would have the autograph independently verified - but authenticators need to see the signature without glass in front of it, and this would need to be cut from the frame to do that. If you wish to take advantage of our usual guarantee, you will have the option of receiving the piece unframed. or having us get it re-framed at your expense.
