Avon bow & butterfly brooch duo

Lovely vintage pieces. The silvertone bow with faux marcasite and teardrop pendant measures 2X1-1/4 inches and is in perfect shape. The golden or brass tone enamel and rhinestone butterfly measures 3X2-1/4 inches and is in good shape, thought missing a half dozen small stones. Both marked Avon, with the butterfly also having the mark SP - apparently not designer initials, but an internal supplier code.
