Grateful Dead Nassau 1973 Poster+Draft Sketch Artist Proof Signed David Byrd COA On the left is David's original concept sketch and, on the right, the final image. About these figures, David says, "This poster was created for Bill Graham after the Fillmore East had closed. As The Dead was a famous boogie band, Bill wanted to do a dance concert with them on the East Coast, something he did every night in San Francisco, but could never do at the Fillmore East as it was a traditional sit-down auditorium. So, he removed all the seats from the huge Nassau Coliseum on Long Island so New Yorkers would be free to Boogie! To his shock and dismay he discovered that NY audiences want to sit and listen, maybe stand in their seats, but never dance. _Hey, where'd all the seats go?Õå It was a swell time anyway!"
