NYC Parks Dept press release of December 4, 1936: "In Manhattan, in Highbridge Park at 167th Street and Edgecombe Avenue the new playground is equipped with wading pool, swings, see-saws, slides and jungle gym for younger children and a large play area with horizontal bars and ladders, basket ball, hand ball, paddle tennis and horseshoe courts for older Children and adults." As can be seen, only the handball court remains and some other kind of game court was added.
