Painted Enamel on Copper Blue Triangular Shaped Dish with Flower

I love the not-quite triangular shape, the bright blue ground, and especially the stylized green stem of the flower on this mid century, painted enamel on copper dish. Vintage mid- to late-60s, it feels quintessentially of that time, with a sense of resolute optimism that makes it very charming still.  7 7/8" widest diameter, 4 1/2" corner to center of opposite side, 3/4" tall. Very good vintage condition, with tiny white speckling to the blue enamel that seems original/indigenous to the piece.
