John Seabury is one of America's greatest poster artists. His work is featured in The Art of Rock books and he has created hundreds of images for events and entertainers. He is the bass player in Psycotic Pineapple. This is a UNIQUE drawing, not a print nor a copy of any kind. The drawing is professionally matted and framed. The exposed area is 10 1/2" x 13 3/4" . Apparently the image is based on a photograph by Hugh Brown. This poster advertises a "Not April First" show by Psycotic Pineapple and Pearl Harbor and the Explosions that happened on March 31,1979 in Oakland.
