Does this building still stand? I can see the “435” on the transom, but I’m not quite sure where this is. Let’s see if the GoDC community can identify this spot and send us the Google Street View of it today. The photo is from the mid-1930s.

UPDATE: It appears that the consensus vote puts this building at 435 M St. NW. And, it’s still there.
This building still stands as a private residence in the 400-Block of M Street, NW.
Good work, sir!
I had the street-view up and the URL was as follows: https://maps.google.com/maps?ie=UTF-8&layer=c&z=17&iwloc=A&sll=38.905966,-77.017411&cbp=13,359.3,0,0,0&cbll=38.905649,-77.017406&q=435+m+st+nw+dc&ei=QxQzUre4CZi34AOHr4DwBA&ved=0CC8QxB0wAA
How about 435 M St. NW? The place next door even still has the window at the very top too. All the trim is the same as the original too. Sure looks like it to me.
