Focus on Peter Getting Out of Nick's Pool and analyze the Description.
The painting measures 152 cm × 152 cm (60 in × 60 in). It depicts the communal pool of the apartment block at 1145 Larrabee Street, Hollywood, north of Sunset Boulevard, which was then the home of art dealer Nicholas Wilder, and shows a naked Schlesinger, then 18 years old, climbing up and out of the pool.  Hockney, in his characteristic style, simplifies and flattens the image, and the rippling surface of the water is abstracted into wavy white lines on blue, similar to a comic or an advertisement.  The straight lines in the painting were created using masking tape.  The work has a border of un-primed canvas, like a photograph, which Hockney says he left "to make the picture look more like a painting".
The figure in the painting is based on a polaroid photograph Hockney took of Schlesinger standing up against the hood of his own MG car. Interviewed about the painting in 2012, Schlesinger laughed about it, saying "That’s why the part under the water isn't painted well—because it was just invented."  In 1967, Hockney's painting won the John Moores Painting Prize at the Walker Art Gallery in Liverpool.  The painting was acquired as a bequest from Sir John Moores who in 1957, established the eponymous biannual award and subsequently often purchased the winning entry and then presented the work to the museum. Moores purchased this work in 1967, and presented it to the museum in 1968. The picture remains in the Walker's permanent collection.
