In 1930 Alfred Philippe became head designer for Trifari. He was fabulously talented and his early designs have become the most sought after by collectors.
Marks used by the company included, among many: "KTF" 1917, "Trifari with a crown" 1930s, "Trifari" with a crown and copyright symbol, after 1956".
The Clipmate was Trifari's patented design. It comprised a pair of dress clips that were fitted on a metal frame with a pin stem. They could be worn together as one large brooch or removed from the frame and worn separately as two separate clips. Coro's version of the same style of pin was patented as the "Duette".
Most of the design patents were registered by Trifari's star designer Alfred Phillipe and thusly most of these beautiful creations are attributed to him. The enamel and rhinestones pins from this era are highly coveted by collectors.
