Max Keil Building is a historic commercial building located at Wilmington, New Castle County, Delaware. It was built about 1875, and modified in the Art Moderne/Art Deco style in 1938. It is a three-story, single-bay commercial building with a rectangular plan built of wall bearing brick construction. The front facade features large display windows on the first floor and an austere, peach-colored terra-cotta wall with a large rectangular display window at the second and third floors.[2] In 2010, it was occupied by an outlet of Rainbow Shops.
It was added to the National Register of Historic Places in 1985.
