Couple of Mourning Dove bounding"1950-60"

Hi
Everyone.

I have this piece of Aluminum Cast sculpture for a while(20 years), i found it at the summer fleat market, Saint-Foy,Quebec.
I was thinking when i buy it , it was Austin sculpture(a collected them at the time)but i look all over the piece , i could't find any maker marking, i know for sure that's from the 1950-60, nice details, incredible patina and beautiful.I still have this one, because, i am a Birds lover.
The bird first instinct at the beginning before forming a couple was to bounded, by kisse earch other, after bound was created, there form couple for life(till something happen to one of the partner)copulation follow and building a nest, could nest more then 4 time during one season,2 or 3 eggs.
This sculpture was 15 inch high by 16 inch wide, on a 9 inch base.

Thanks for Viewing.
Alan
