1.75” button with name of maker on curl “Zeidler & Zeidler Ltd. L.A. Calif.” Button shows symbolic cool wolf with phrase “Have Mercy, Baby!” Wolfman did his show on this station December 3, 1966 through April 14, 1972 and we think this button would date from the earlier years of that time frame. There are about a half dozen ¼” to 1” scratches that show mostly just in reflected light. In some angles they are obvious but viewed directly the only thing that shows is a tiny white mark at the center of the word “Baby.” Extremely limited distribution and the only example we have ever offered.
