3409 Mirasol Avenue

This mark, by a Fruitvale contractor, feels out of place here—earlier than the rest. I have since found another one on Excelsior Avenue.

Peralta Avenue is now known as Coolidge Avenue. The street was renamed after Oakland annexed this part of town in 1909, so that puts this mark in the first decade of the 1900s if not before.
