Green Day Concert Poster, Foxbro Hottubs Original Screen Print Limited Edition. Signed by designer, numbered artists proof. SIZE 11X24 inches on heavy poster stock. Genuine, authorized concert posters. It has been in my flat file for many years. Artist proof out of my stash. After this no more will be available. I’m friends with Kevin Preston, he hooked me up with this job. He is playing with Green Day now. He can vouch for the authenticity and my existence. I never re-print anything, that’s dishonest.
