White Rectangles, Number 3 (1939) is filled with white, blue, gold, and rust-colored geometric shapes that produce a collage-like effect. Some of the forms, particularly those near the center, are defined with strong black outlines, while various patterns and textures articulate others. Artist Irene Pereira (1907 – 1971) used a number of different tools, including, possibly, the blunt end of her brush, to carve into the paint surface, creating troughs that enhance the paints physicality and, in repetition, suggest industrial production.
Pereira made this work while a member of the Design Laboratory, a cooperative school of industrial design established under the Works Progress Administration. The school advocated applying abstract design principles not only to painting and sculpture, but also to industrial design and even architecture.
