"Renaissance Thinking About the Issues of Our Day"
See the "upside-down stars" pin images in this blog. There are several RNC pins on eBay that show a date of 1996. This one I found with a date of 1984 from the Dallas Republican Convention. Here is another where the elephant doesn't face right, it faces left. "Peanut Buster" pin is from the campaign to defeat Jimmy Carter in 1976 or 1980.
