A few weeks ago I came across this vintage ad from a medical periodical, "The Bulletin" [c.1922]
The RADIUM & Oncologic Institute, 1151 W. Sixth Street, Los Angeles"

detail / 1922 Advertisement
I thought I'd check the address and lo-and-behold both buildings are still standing (albeit remodeled)
-I wasn't sure it was the same building until I noticed the unique arched windows on the side facing Lucas Ave.

The somewhat ornate front entrance has been moved from the center of the building to the right side--->
Recently, the building has seen some upgrades.

It's much more ornate than I expected. (is this the same building?)
