Measuring 1.5 inches.  Rare, early button from the California Aircraft Institute, a school training people in airplane construction and repair.  Likely dating to the 1930's with the paper label of Western Badge & Button Company of Los Angeles.

A handsome, well preserved example.  The front is clean and free of damage.  Back with just a bit of wear along the metal ring.

First button ships for $3.00.  All additional buttons ship for free.

We have purchased a collection of nearly 20,000 pinback buttons.  Many of the buttons of Minnesota or North Dakota interest.  A few books full of political.  Many sports related buttons and much more.  We will be steadily listing new buttons for the next few months.
