Vintage Silvertone Leaf Pendant/Brooch (pin) with Pierced Earrings

This vintage silvertone leaf jewelry set includes a convertible pendant-to-pin and a pair of matching pierced earrings in their original box. There is no brand identity. However, this appears to be a fine quality fashion set that would have been sold at a department store. The note on top of its box states it was purchased by its last owner in 1975 at a lawn sale craft outlet in New Hampshire.
