Starting on Columbus Ave. on the Upper West Side of Manhattan, 
then moving west, to Riverside Drive,  Prof.John Hart graphically demonstrates the basics of One Point Perspective, with the use of his selected imagery as a  stunning visual demonstration of the   Horizon Line, the Vanishing Point,  ( stating that its not a stationary dot on a drawing but a moving entity ), and the  projected diagonals.emanating from the active vanishing point.
More fun than a, 'What's this?' flat drawing.
