A set of Two matching Antique Brass Keyhole Cover made in France in the 1900s.
I have not polished them. Dark with patina.
The pieces measure each 5.5 in diameter approximately
or in inches 2 1/8 inches in diameter approximately.
One piece has three tiny holes to secure to surface but the second one has no holes but places for little screws on the back.
Nice casting.
