Here are a couple of Julius Shulman pictures showing two different branches of Buffums' department store. This is
"Job 3842: Buffums' Stores, 1965".
Both from
Getty Research Institute
I tracked the first store down to E 3rd and S Linden Streets in Pomona. The building now belongs to the Western University of Health Sciences. I went back a couple of years to get this GSV image with a wider angle. The street on the right is now closed to traffic and paved over.

The other picture shows the original store on the corner of Pine Avenue and E Broadway in Long Beach. We've seen the Long Beach store a couple of times before - check out

post #20378. A page on Buffums' at
www.thedepartmentstoremuseum.org says that the business started in 1904. It dates the building on the right of the Shulman Long Beach picture at 1914, with the six-story addition added in 1925. It even includes a store guide. Sadly, these buildings have now gone.
