BUTTERFLY Earrings in the Original Packaging

Earrings - Sarah Coventry. "BUTTERFLY" from 1957. Incredibly detailed goldtone 3-d butterflies with black and yellow enamel. Clip. 1" long, 1 1/4" across. Excellent condition in the original clear dome packaging, on the original card. I removed these gently from the card but I do not think they had been removed prior to that. Not marked, but shown in the Sarah Coventry color Cardex files. Also shown in the Schiffer Collector's Guide by Sturdivant and Crabtee, page 51. Cardex files and Collector's Guide not included.
