I was so impressed when I discovered the portraits of Lotte Meitner-Graf, who made wonderful photographs of artistic and scientific worthies of the 1930s to the 1960s, in her London studio. Many of her best portraits can be seen at the website of the National Portrait Gallery in London, but there's another source for fabulous shots: LP covers.
Carlo Maria Giulini looks as refined as his Dvorak sounds, in this 1962 album cover portrait by Lotte Meitner-Graf.
