Donald Duck and Mickey Mouse wood composition pin back buttons (1938)

I am not a pin back button collector of new buttons but a few of the old ones I like to wear. This exquisitely colored Walt Disney character jewelry was made by the Brier Manufacturing Co. of Providence, R.I. These and a couple more of Mickey playing other instruments can be found on page 15 of the Walt Disney Character Merchandise Catalogue for 1938-1939.--- With the addition of Mickey on the drums as far as I know I am missing only Mickey playing a trumpet.
