Vintage 1970 large enamel flower pin

Vintage 70's enameled flower pin. Large blue flower with green highlights at edge. Yellow center details. This beauty measure 4 3/4" Tall Width: 2 3/4" A few marks and very subtle chips to enamel, mostly on leaf and stem. Not noticeable when worn-see photos. I used to have a sundress that I wore this with, I think it would wear well with a dress I have listed which has the same colors in it.
