There are two paintings in the collection with this title. The geometry and construction of the two are identical (see painting #100 - 1979.1093.67).
The only differences between the two paintings are the color scheme and the dimensions. This painting has a black and purple background and a white rectangle that represents the square root of pi. The method of the color scheme is similar to painting #89 because, like the electric blue rectangle in the other painting, the white color of the rectangle against the purple background creates a dramatic contrast that highlights the crux of Crockett Johnson's construction.
This painting is #89 in the series. It was executed in oil on masonite, and has a black wooden frame. It is unsigned and undated.
