This stamp is on the west side of North Clemens Avenue between Jerome and Vine and it’s notable for being the first dated BdWL stamp I have come across. Now I have an idea of the time period in which BdWL, whoever that is, was operating.

As noted in the past, I have no information about BdWL, including what the initials stand for. It occurs to me that one reason to use a lower-case d would be if the initials were a name, and “d” was “de” or “du.” [Something] de Waal [Something], for instance.
