Crowded Lecture Hall in the A&I Building, by Unknown, c. 1890s, Smithsonian Archives - History Div, The lecture room in the West North Range in the United States National Museum, now known as the Arts and Industries Building, is crowded. On the back wall of the room are the spectacular Catlin Indian Gallery, portraits of Indians and scenes of Plains Indian life drawn by George Catlin between 1832 and 1840. A stuffed bear along with other animals and an Eskimo mannequin has been placed in the front of the hall probably to be used for demonstration purposes..
