The first 5 items are each 1.25", four have backpapers but the "Indigo" bunting does not. The "Indigo" bunting, Cliff Swallow and Red-Headed Woodpecker are Exc. and display Mint. The buttons for Kingfisher and Blue Jay each have several small craze lines in the celluloid but still display quite nicely. Of the four Audubon Society buttons, the first is .75" and the other 3 are 7/8". The first 3 are celluloids and the last is a litho. The next 11 are 13/16" lithos from a 1930s set of 40. These 11 are Bobolink, Chicadee, Flicker, Magpie, Rose-breasted Grosbeak, Song Sparrow, Summer Tanager, Western Tanager, Wild Duck, White Winged Crossbill, Yellow Warbler. Crossbill has single tiny paint mark but the rest are essentially Mint.
