Matchbox Structures

Lygia Clark (1920 – 1988) was a Brazilian artist best known for her interactive sculptures such as these small matchbox structures resembling modernist architecture. The matchboxes, small, delicate and intriguing, and susceptible to manipulation at will by the viewer, were "a different experimental attempt by Clark to heighten the perceiving subject sense of their own subjectivity, and were also among the last such art objects ever made by the artist."
