3108 Lewiston Avenue, Berkeley
I have Griset marks from 1950 to 1958, but most of the dates are rare.

I have only a single Lee J. Immel mark from Oakland, which I think is older than this one.

Very interesting: besides being the first hand-drawn mark I’ve found by Hayward contractor Lee Railsback, this sprawling example in a driveway shows that he signed his name Railsbach. Also note the “Greek E’s” he used.
