Sizes are 5/8" to 7/8". Those which came with back paper have it and most of them from W&H. All but the center two buttons of the third row are celluloid. These other two are litho. The first button in row three relates to women acquiring the vote for the 1920 election. This reads "My First Vote Is For Harding." Reverse of this has trivial 1/16" cello split on the back both at the top and bottom, just enough to make a tiny edge bump when viewed from the front. The larger litho button has a pair of 1/16" tiny scratches. The other eight buttons are NM to Mint. Julie Powell Collection.
