Majestic Brown Velvet Evening Bag W/Hidden Zipper!

I adore this bag! It is in excellent condition, with the exception of some small patches of gold on the top that have flaked off, leaving silver underneath. I just discovered the hidden zipper tonight - and I am guessing most have missed it! Please feel free to ask questions. This is a vintage bag that I need to learn more about. Length: 5" Width: 9"
