Grateful Dead What A Long Strange Trip Signed Record

I have up for sale an autographed copy of the Grateful Dead’s What a Long Strange Trip it’s Been vinyl record. I have this set for a low asking price, because I cannot confirm the authenticity of the signatures. I acquired this signed album here on Pricetronic in approximately 2006 and have had it stored safely ever since. Sleeve and vinyl records are in good shape. Please reference photos as part of the description and feel free to send me a message with any questions.
