1.25” with outstanding multicolor which includes small illustration at bottom center of Theodore Roosevelt in Rough Rider uniform holding a saber aloft as he charges on his white horse. The button is NM and displays Mint as made although, as with most examples, design is 1/16” off center. This example is complete with its Baltimore Badge back paper which is the original, although the collet has the “Phelps 1899” patent date. The celluloid has mirror-like gloss and beautiful intense color.
