Wholesale Composition with the Yellow Half-Moon and the Y (1918)

This intriguing piece uses geometric abstraction to explore cosmic and mystical themes. The dominant yellow half-moon and the stark 'Y' symbol stand against a textured backdrop of deep blues and reds, evoking a night sky. Klee’s work here is a fine example of how he used abstract shapes to weave complex narratives, suggesting celestial movements and astrological symbols.
