Libby Staub signed her works as, "Drop Shadow Signs." This mural covered the window of a closed store on Grant Avenue in North Beach, San Francisco.

The mural depicted a rainbow behind pink clouds with large flowers in the foreground, and a white cat in the lower right corner.

The other half of the mural was on the other side of the door, and this other half lacked a signature and a cat.
