Massive Orchid Brooch

Here is another Brooch found today at the yard sale, a massive orchid enamel and brass Brooch, would say from the 60s-70s, could be little older, don't know for sure, this is not the first orchid brooch that I found over many years, but that's the biggest.
This brooch is 2.50 inches high by 2.50 inches wide.

Many thanks for stopping by.
