Gargoyle Fireplace cover

I bought this today, when I first looked at it I didn't know what it was til I unfolded it out, it's 24 1/2 inches tall and 37 1/4 wide. They had vintage gargoyle fireplace screen 20 % off WOW I bought it for $30 dollars and its solid brass looks like it's never been used no heat Mark's or nothing on it. They make Peacock screen. They said 1940's
