With reference to the Vermont panorama above, one of the few survivors on that section of Vermont Avenue is the building on the corner of 3rd.
Detail of panorama above.
The modern signage does little to accentuate the building, but otherwise it looks intact.

The current view looking west on 4th Street shows that the Park Lane Apartments (3333 W 4th St) and the church on the west side of New Hampshire are still standing. The church still looks beautiful, although I'll wager that it wasn't the Korean Philadelphia Presbyterian Church when the panorama was taken!

On the left of the view above is another roof sign. By chance, I found a postcard of the Brynmoor Apartments on Ebay a few weeks ago, and didn't even know it had a roof sign.

The roof sign is at the back, so was obviously meant to be seen from Vermont and 4th.

Other than the windows being changed, the wall and arched sign at the entrance seem to be the only alterations from the postcard.
