I have another Dan Doyle mark from this year, but that one has the date inside rather than below the mark.

Every now and then I glean a new fact about Oakland’s sidewalk contractors. From this hand-drawn mark I now know Hennig’s first initial. This pushes his dates into the 1940s; they go back to 1928 (so far).
The web suggests that this was Otto Albert Hennig, a German immigrant who left a son and three daughters in Oakland. He lived at 3527 Suteo Street (that must have been Suter, in upper Allendale) at the time of the 1940 census.
