1920s (pre-1924): W. 102nd Street Looking SW toward Riverside Drive and W. 101st St.
What I would LOVE is for some kindly neighbor at the Broadmoor somewhere up top to try to capture a modern day image looking west southwest out toward West End Avenue and the river over the rooftops.
This picture is a gem for, really, how much has remained so. The east side of West End Avenue both north and south of W. 102nd Street should be familiar to viewers as should be 855 West End Avenue dead center with its nearby neighbors, just as you'd see them now. I love it for the way 299 Riverside at the south corner of W. 102nd Street and Riverside Drive dominates the view. And for the absence of 300 Riverside Drive. You'll note that William Foster's second mansion sits where 300 Riverside Drive is today at the north corner of W. 102nd Street. Scroll down for an image of that house, built in 1888 by the glove mogul, and read more here, in Gary Dennis's blog, about the two Foster mansions that occupied that lot.
Of course, 865 West End as we know it today hadn't yet gone up, and the shot is remarkable too for a rare shot of the row of houses at the northwest corner of 102nd Street and West End.
Ah, but look at Jersey!!
