This is one of the few statues that Bugatti did not edit through the Hebrard foundry.

He gave two plaster casts (of a male and female condor) to Michel D'hoest the General manager of the Zoo of Antwerp. These original plasters had a silver patina, which Rembrandt Bugatti applied. This cast is a posthumous cast by the Valsuani foundry (probably dating from the 1930s), bearing the Valsuani foundry stamp and an edition number (2/25).

The patina is very similar to the cast represented by Veronique Fromager in the catalogue de l'oeuvre raisoné on page 222.
