Recently I noticed a listing on Ebay while searching for "Kennedy" and "Harlem" that showed Robert Kennedy somewhere in Harlem:

The most obvious location information is on the right-hand side - the 111th Street sign with a fuzzy/illegible cross street.  Other clues as to the location are that the photo includes a Botanica (suggesting more east, than west Harlem). 

And then there is his height above the street (that's a man's head with a hat, next to a parking meter in the bottom right corner. 

Lastly, we're looking at the northeast corner of an intersection given the one-way street sign and the direction of traffic on 111th Street.

First I used Google Street View to "go" across 111 to see if the architecture lined up with anything.  It didn't, which led to several possible locations - ones where there is no longer a building (think Lex/111's northeast corner) or where there is a new (post-1966) building (think Madison/111's northeast corner).  

So I had to go back in history and use the 1940's tax photos:

and 'traveled' across the street looking for architectural equivalencies.  It turns out that the photo of RFK shows a building that stood at 111th and Park:

Note the distinctive masonry treatment above the windows.  Note the bricked/closed window behind Kennedy's head, and note how there is just a 2 story building to the west of the main tenement building.

To see and explore the tax photos (and see the 1940s and 1980s versions) cick here:

(​Kennedy is standing on the now closed off 110th Street stop of the Metro North train line.  Yes, there used to be a train stop at 110th Street and Park Avenue, but it's been bricked up for decades, now).
