Lichtenstein was commissioned to create a large public work in the Equitable Tower.

He "selected the motifs, he made a series of drawings and then collaged them together to make a maquette, measuring 34.25 by 17.5 inches, which became the working plan for the actual mural.

Analysis of his work refers to non-rectangular canvases as imperfect paintings and are described as being characteristic of Frank Stella.

Mural with Blue Brushstroke is regarded as Lichtenstein's first 'imperfect' painting due to the depiction of a carpenter's triangle and French curve.

It marks a commitment to art on the part of a prominent American corporation that is as generous and innovative as any before.
