This is a Wonderful Vintage Modernist Leaf Brooch by the well-known Modernist Jewelry maker, Pedro Pujol. He was a Contemporary of Rebajes and possibly his half-brother. His works seem to be harder to come by than those of Rebajes.
It measures 2 1/2" across x 1 3/8" and is in Good Condition. The soldering to the pin back is a bit sloppy, as I have seen on several of his items. It is signed ORIGINAL HANDMADE Pedro Pujol
