In celebration of Mother's Day on Sunday, the San Francisco Museum of Modern Art is offering free admission to the opening of their new Rooftop Sculpture Garden. The Rooftop Garden features two open-air spaces and a glass pavilion with views of both the San Francisco skyline and the museum's sculptural works.

Sculptures will be comprised of works that were either recently acquired by the museum or that are rarely seen. Highlights include Alexander Calder's Big Crinkly (1969), Ellsworth Kelly's Stele I (1973), and Barnett Newman's Zim Zum I (1969). Also on view will be recent gifts of artwork donated specifically for display in the new space, including Mario Merz's The Lens of Rotterdam (1988) and Joel Shapiro's Untitled (1983-87).
