We work closely with our colleagues at National Portrait Gallery, Smithsonian Institution. The NPG received a major gift to its collection of more than 100 Karsh portraits in 2012 and due to the popularity of the work they use the images for various promotions and products. This year they will update their National Portrait Gallery/Smithsonian American Art Museum Commemorative Guide featuring important works from their collection, and include this portrait of Muhammad Ali.
