Keyholes, 2 pairs, man and woman, top copper circa 1970

Pair of keyholes facing each other.
A man and a woman face each other and are holding the keyhole itself.
Really unusual and rare.
It can be used for a double door or both sides of the same door.
The metal is probably copper coloured in gold and bronze.
It has a patina of time and should be brighter after cleaning.
I have 2 pairs but the price is for only one.
All the nails are present.
Dimensions; 15/13 cm or 6”/ 5 1/4” top
