A remarkable relic, being one of Chuck Berry's trademark aviator hats, heavily worn and sweat-stained, boldly signed on the top with his autograph signature and a smiley face, and on the rear panel by Bo Diddley, who adds the year 1963. The two legendary R&B musicians were friends and Chess Records labelmates at the time. One year following the signing of this hat, they released the studio album "Two Great Guitars: Bo Diddley/Chuck Berry," now considered to be one of rock music's earliest "super session" albums, consisting of two lengthy and spontaneous instrumental jams plus a couple of recently recorded instrumentals by the two guitarslingers. ***Please note that the image of Berry wearing a similar hat is provided in the listing for reference only.
