1957 Oklahoma Semi-Centennial Arrows to Atoms Medal

This is a bronze commemorative medal from the 1957 Oklahoma Semi-Centennial Exposition. One side features the Statue of Liberty and the Liberty National Bank and Trust Company of Oklahoma City. The other side shows the 'Arrows to Atoms' logo with the dates June 14 to July 7, 1907-1957. It's in decent shape with some natural patina from age. Just clearing out some old collectibles. Very fine condition
