Between 1957 and 1965, National Gallery School alumnus Douglas Green worked part-time as a high school art teacher at Bonbeach High near Frankston. The schoolyard is based on sketches he made during this time and depicts a queue of schoolboys drinking bottles of milk likely provided by the state government’s free milk program of the 1950s. A study of childhood and school life, the painting also reveals Green’s interest in geometry and composition. Angular, fragmented forms in muted tones are used to articulate the scene; the surfaces of the schoolyard, buildings and uniformed figures vibrating against each other.
