The Philadelphia Spectrum was a familiar venue for the Grateful Dead, who played 53 gigs there during the Jerry Garcia era. This show contained many of their newer compositions, including Liberty, which inspired the design of this Tour Issue hat. What better locale than Philadelphia, home of the Liberty Bell? Featuring a relaxed, un constructed profile, this Grateful Dead baseball cap will fit most Dead Heads, and is adjustable by a cloth strap with a metal slide buckle closure. Made of 100% cotton enzyme-washed polo twill fabric.
