Vintage Accordion Cufflinks. Squeezebox Cufflinks. Folk Cufflinks.
Vintage accordion cufflinks circa 1950's-60's. These "squeezebox cufflinks" look just like an accordion on the tops, including the keys done in enamel paint. Backs read PAT PEND which is common to 1950's cufflinks prior to being patented. One cufflink does have some dark areas around where the shaft was attached but this can be common when they are heated and put on. The high temperature will occasionally "blacken" the metal. This will not affect wear. The whale toggles work very well.
