Retro Pink and Black on silver tone metal cuff links and tie clip

This great retro style set of cuff links and matching tie clip remind me of the 50's. The pink and black enamel with overlying silver tone metal scrollwork accents the cuff links and the tie clasp. They are unmarked with the exception of a patent number on the backs of the cuff links. The patent number is 2472958. The circular discs are 1 inch in diameter. The tie clip is 1 3/4 inches in length.
