Each is 2-3/8". Two are in brass luster and three are in green coloration as issued and one seems to be brass missing the luster. This is the item that has a fraternal star and symbol design on the shell. This is also the one piece that has a good bit of browning to the celluloid. The other pieces promote Eagan Business Schools, Whitehead & Hoag Advertising Specialties, a company called "Billups", and a San Francisco fish restaurant. This cello has scattered but small dots mostly at the rim edges with just a couple on the interior. Three of the five are Exc. and display Mint. Also see early turtle pin #780. From the Julie Powell Collection.
