This mark is at the door of the cute little Haley Law Office building. It’s a much better example than the other one I found last July.
The Gray Bros. A.S.P. Co.

1700 block San Pablo Avenue
This is the building that Piedmont Piano is in, but at the other end. Presumably the Gray Bros. were the overall contractor. “A.S.P.” stands for Artificial Stone Paving, a common name for concrete formulations in the late 1800s. The Schillinger Patent was the impetus for a major court case in 1894, Schillinger v. United States.
As of 1897 the Gray Brothers operated two San Francisco traprock quarries, at 26th Street and Douglass and at Green and Sansome.
