Smallest item is in top row and 11/16" very early and beautiful celluloid lapel stud for meat cutters and butchers. Largest button is at bottom right and 4" dia. The upper third of the buttons in our photo are c. 1940's and earlier including a pair of delegate badges. Lower items are mostly from the '60's and newer including several elaborate delegate or guest badges to conventions ranging between 1989 up to 2004. An extremely clean group in Exc. to essentially Mint condition. Many very limited issues.
