We scored a preview of the new Cleveland Museum of Art exhibit, which opens Sunday, April 30. At a time when abstract expressionism dominated the international art market, Alex Katz combined abstraction with recognizable imagery by reducing his compositions to their most fundamental elements: line, form and color. In hindsight, these compositions foreshadowed the rise of pop art in the 1960s. The exhibition remains on view through Aug. 6. Tickets for Brand-New & Terrific: Alex Katz in the 1950s are $12 for adults; seniors and college students $10; children ages 617 $6; children 5 and under free. Museum members free; member guests $6.
