[4] A record dated 1636 of the artist acting as a witness for Guillam Forchondt and N. Lemmens is evidence that he was still in Antwerp at the time.
[2] De la Vallee worked for the Forchondt workshop, which was one of the most important exporters of Flemish art to all corners of Europe and to South America.
[3][5] Many of the works produced in the Forchondt workshop, including those of Gerard de la Vallée, used copper as the support.
From Seville the artworks where shipped through Cádiz to Vera Cruz (Mexico) where they were sold to local convents.
An example is the Wooded Landscape with the Virgin, Christ Child and Saint John (At Lempertz on 21 May 2016, Cologne, Lot 1256).
