The Friday presentation comes a day before a family festival at the museum with Snoopy and a screening of the film, "It's the Great Pumpkin, Charlie Brown."
Schulz died 10 years ago and Saturday marks the 60th anniversary of the "Peanuts" strip. It continues to appear in more than 2,200 newspapers in 75 different countries.
The photograph of Schulz by portraitist Yousuf Karsh is the gallery's first image of the famous cartoonist. It depicts Schulz at his drawing board with a partially completed comic of Charlie Brown and Lucy.
