A scarce boxing-style concert poster for a date on the Ozzy Osbourne “Blizzard Of Ozz” tour– May 20th 1981 at the Riverside Theatre in Milwaukee, WI. The poster proclaims “Black Sabbath’s Legendary Former Lead Singer’s First Solo Album and Tour” (both with the late Randy Rhodes) and notes at the bottom “SO DEVASTATING IT’S UNNATURAL!” In excellent condition with two sets of barely noticeable staple holes along the top, faint moisture spotting visible on the back only, and a slight crease in the upper right corner. 14″ x 22 1/2″. A classic.
