Sizes are 13/16” to 1.25”. In row 2 the first and third are litho and the one in row 3 is a litho with the rest being cello covered. Group begins with the classic and historic “The Montgomery Ward & Co. Electric Horseless Carriage.” Missing its back paper but known to be from 1898. Front has a single pinpoint nick upper left and a faint .5” vertical scratch barely seen even in reflected light. The button still displays beautifully. Next two are early issues from the “American Locomotive Motorcar” and “Rickenbacker Motor Co. Detroit.” Buttons in row 2 are for Oakland, Cadillac and Hudson. This has a few pinpoint dots off extreme edge. Last reads “Kaiser/Frazer ‘49” and is a rarity. All are NM displaying Mint except as noted.
