1.25" with backpaper by maker Pacific Regalia Company. We've seen this once in a large 1.75" size. This 1.25" has the same design consisting of a purple umbrella which stands on a bird-foot shaped base flanked by a pair of seated green frogs with Mt. Tacoma (later named Mt. Rainier) in the background. Curl of button reads "Copyright 1905." Only example we know of in this size and in Exc. condition, displaying Mint. Morry Greener Collection.
