I used to go down to St. Marks Place in Greenwich Village in the 1970′s and 80′s to a record store called Sounds. I got all kinds of promo and autographed records there. There was never a certificate of authenticity offered, and to be honest, I never needed one for myself. This is a vinyl LP of Blondie’s Eat to the Beat LP autographed by Debby Harry boldly across the front. I didn’t see her sign it, but I believe it is real. There are no scratches or blemishes on the vinyl. The generic white sleeve has a split in it. I have 100% perfect feedback, which means no one has ever been disappointed in my listings.
