As far as I can see there aren't any clues available to figure out the location (
or the people) in this rppc postmarked Los Angeles. [August 21, 1905]
eBay
It appears to show the man of the house
(or hotel?) posing with the hired help.
Here's the reverse with the Los Angeles postmark.
............................ Hey! ..maybe there
is a clue.
p.s. The more I think about it..this is part of the Michigan address.
I got all excited for nuttin'.
