Further information
In Four Numbers Summing Thirty, the overall composition is driven by numerical logic. Each shape is defined by the number it contains; the hexagon, for example contains the number 6, and the nonagon a number 9. Robert Indiana’s guiding logic extends to the number selection, as all consecutive numbers from 6 to 9 equal 30.

As self-referential as the painting may be, the style of each painted number is rooted in the urban environment. Bright colors reflect city lights and high-key color ads, and the style of each number recalls stenciled numbers on buildings and sidewalks.
