Convex and Concave 1955

"Convex and Concave" (1955) is a lithograph by Dutch graphic artist M.C. Escher, renowned for his impossible spaces and intricate patterns. This artwork exemplifies Escher's mastery of perspective, creating a visually perplexing scene where stairs lead both upwards and downwards simultaneously. The viewer is challenged to reconcile the impossible architecture, questioning the very nature of space and perception. The use of black and white further enhances the illusion, highlighting the interplay of light and shadow that contributes to the disorienting effect.
