to the department in 2015. Pablo Picasso's Old Guitarist, Henri Matisse's Bathers by a River, Constantin Brâncuși's Golden Bird, and René Magritte's Time Transfixed are highlights of the modern galleries, located on the third floor of the Modern Wing. The contemporary installation, located on the second floor, contains works by Andy Warhol, Cindy Sherman, Cy Twombly, Jackson Pollock, Jasper Johns, and other significant modern and contemporary artists. Photography The Art Institute didn't officially establish a photography collection until 1949, when Georgia O'Keeffe donated a significant portion of the Alfred Stieglitz collection to the museum. Since then, the museum's collection has grown to approximately 20,000 works spanning the history of the artform from its inception in 1839 to the present. Prints and Drawings The print and drawings collection began with a donation by Elizabeth S. Stickney of 460 works in 1887, and was organized into its own department of the museum in 1911. Their holdings have subsequently grown to 11,500 drawings and 60,000 prints, ranging from 15th-century works to contemporary. The collection contains a strong group of the works of Albrecht Dürer, Rembrandt van Rijn, Francisco Goya, and James McNeill Whistler. Because works on paper are sensitive to light and degrade quickly, the works are on display infrequently in order to keep them in good condition for as long as possible. Textiles The Department of Textiles has more than 13,000 textiles and 66,000 sample swatches in total, covering an array of cultures from 300 B.C. to the present. From English needlework to Japanese garments to American quilts, the collection presents a diverse group of objects, including contemporary works and fiber art. Architecture The current building at 111 South Michigan Avenue is the third address for the Art Institute. It was designed in the Beaux-Arts style by Shepley, Rutan and Coolidge of Boston for the 1893 World's Columbian Exposition as the World's Congress Auxiliary Building with the intent that the Art Institute occupy the space after the fair closed. The Art Institute's famous western entrance on Michigan Avenue is guarded by two bronze lion statues created by Edward Kemeys. The lions were unveiled on May 10, 1894, each weighing more than two tons. The sculptor gave them unofficial names: the south lion is "stands in an attitude of defiance", and the north lion is "on the prowl".
