4206 Atlas Avenue
My other example from this year, Poblitz was careful to include his phone number, but this time he didn’t care.
Young Avenue
Only the shape of the oval and style of the numbers gives this away as a McCaffrey mark. Unlike my other example, this one has normal-sized numbers.
“4299” Detroit Avenue
A. Casqueiro started out with a nice 1928 stamp but didn’t update or replace it, and well into the 1930s he just scratched the real date next to the original bronze numbers. After a while he filed off the date and the address as well. By 1939 he’d gotten a more elaborate stamp that he used into the 1950s. Having learned his lesson, that one didn’t have a bronze date at all.
3616 Monterey Boulevard
I also have an example from this year with a hand-drawn date. But this mark shows that he already had a nice ready-made stamp with the date in January, while the other mark is dated in late May. My hypothesis is that he found changing the mark each month (see 1928) was too much bother, and hell, why get a new stamp each year either?
4284 Detroit Avenue
This appears to be the year that L. M. Rasmussen changed his practice to a formal company, Rasmussen Co., and got himself an elegant new stamp.
