The entrance to Central Park that I was most familiar with as a child, approached by walking up 60th Street from Amsterdam Houses on the far west side. The traffic circle has been modified a few times since this picture. It's still a busy intersection, but much easier to navigate for drivers and pedestrians, I think.
So glad I found some streetcars! I've enjoyed The Daily Postcard's Streetcar Sunday for a while and I'm happy to link to the fascinating post there today.
