Great pair of Art Deco style dress are from the 1930's. These are not signed but do have a 7 digit utility patent number on the back most likely for the clip mechanism. These are nice and tight; they feature rhodium plating which is in good condition and very shiny as though they were made last year and not over 80 years ago! It's always a pleasure to find a pair of these especially when they are in such nice condition! They each measure 1 1/2 inches long by almost 3/4 inch wide.
