Smallest is .75" and largest is 1.25". Several of the scarcest in the group are row one, #1 depicting the "Aviation Building." Second is almost as scarce and shows "New England Exhibit" with the ship 'Yankee.' This is a real photo button. First in row two features movie star William Holden and names the movie title "Golden Boy." A little air under the cello changes the yellow tone a bit but no actual stain except at the very bottom edge. Second in row two is also scarce and promotes "Guernseys" cows. Last is from the Borden exhibit and repeats the oft asked question at the fair "Where's Elsie?" This is actually a scarce button. Among the final six is a single day issue for "Finland Day" in 1940. All are NM displaying Mint except as noted.
