These rose gold top cuff links have the old kidney shaped rigid brass bar attached to an oval top.  The top is engraved with a nice swirling pattern suggesting an oriental styled theme of ocean waves.  The waves are engraved with very fine lines contrasting the brite cut metal behind them.  The remainder of the oval has a dull finish to contrast with the brite finished edge.  The back of the "kidney" or the part exposed when worn is also coated with rose gold which is worn in spots.  Circa 1910, these cuff links measure 3/4" long by 1/2" wide and are marked on the shank "G.L.P. Co.", George L. Paine Company operating in Attleboro, MA.
