Measuring 16"Wx12.5", here's a tin poster sign featuring an image of the Silver Surfer, sentinel of the space-ways and one of the few subscribers to the monthly "Cosmic Pontificator" Magazine.  Yep, they still offer it in the Goffabrida Cluster, just 24 Hoolatrons to the left of Salsbury Planet!  Stop shaking your head!  This Silver Surfer could atomize you from 30,000,000,000 light years away.  He can hear your molecules scraping and it bugs the holy heck out of 'em!  Stick up this tin sign and thank the Surfer for not listening in on your less than considerate molecular structure!
