Following the opening of Krannert, the expansion continued with the Clowes Pavilion in 1972, which housed the Clowes' collection of Old Masters. Construction on the Showalter Pavilion and Sutphin Fountain was completed in 1973.[5] In 1986, the IMA's board members chose Edward Larrabee Barnes to design the Hulman Pavilion, a new wing of the museum which housed the Eiteljorg collection of African and South Pacific art. The pavilion opened in 1990 and increased the exhibition space to more than 80,000 square feet (7,400 m2).
