Each is 7/8” and all have their backpapers. Only condition issues are on the last 2 in top row. “Pope” has trivial .25” hairline split on reverse but cello lays flat. The “Swell Newport” has some lt. gray perimeter stain but still strong color. Rest are Exc. The only button not from the turn-of-the-century era is from 1922 for “Boston American Social Bicycle Run.” Two buttons display the “LAW” logo and two buttons are for the “Monarch” bicycle but totally different designs. A nice group of scarce buttons.
