Early conceptual sketch for building plan, National Gallery of Art East Building (architectural drawing (visual work); I. M. Pei (American architect, born 1917 in China); Fall 1968; Gallery Archives ; unavailable)

Note: In a moment of insight, I. M. Pei solved the problem of the site's irregular shape by dividing it into an isosceles triangle and a smaller right triangle. He later recalled, "I sketched a trapezoid on the back of an envelope. I drew a diagonal line across the trapezoid and produced two triangles. That was the beginning." This early sketch shows the division of the site into two triangles. The West Building is represented by the lines to the left of the drawing, with the arrow suggesting its strong east-west axis.
