Exceptionally large 2-1/8” in striking black on bright orange colors produced for “1952 National Dealers’ Sales Conference.” Button’s reverse has tiny 1/8” paper dot off extreme outer edge of backpaper by Whitehead & Hoag. Reverse collet has just the most trifle bit of oxidation on a 1” segment of the gray-colored collet. The celluloid front of the piece is in N. Mint condition and displays essentially Mint. Perfect centering and high gloss. The only example known to us.
