Smithonian Archives' Assistant Archivist Ellen Alers responded,
"Chalk Talks" (nine in all) were held in the auditorium at the then Museum of History and Technology (what later became the National Museum of American History). These accompanied the exhibition titled, "Cavalcade of American Comics" that was on display at the Museum of History and Technology, May 2 - July 6, 1966. The exhibit was co-sponsored by the Smithsonian Institution, Washington Evening Star, and Washington Post newspapers.
Cartoonists who gave these talks included: Chester Gould, Allen Saunders, Alfred Andriola, Walt Kelly, Al Capp, Stan Drake, John Liney, Milton Caniff, and Hal Foster.
There is one box containing material from this exhibition and it is Record Unit 334, box 23. It is stored off-site so you'll need to give at least one week's notice before visiting.
I think I will take her up on that and perhaps do a short article for the International Journal of Comic Art at some point. Did anyone else see this show? If so, please leave a comment.
Joel's friend Charlie Roberts contributed his memories of attending:
Due to my work schedule I could only go to the Capp and Caniff talks. A few anecdotes. Al Capp was going to the car afterwards with Art Buchwald. He was pretty grouchy, and wouldn't sign an autograph but Buchwald said "Aw Al, sign the autograph for the kid" and Capp begrudgingly signed . I thanked Art, and Thank him again today (!) Caniff gave a chalk talk, and couldn't have been nicer on and off the stage. I talked to him afterwards about getting a drawing, and he gave me his address. I wrote him, and he sent me the original art to a Steve Canyon daily strip. My First original, inscribed and dated June 1966 ( yes, I still have it!), which led to a lifelong collecting interest in original art as well as appreciation for Caniff art and the artist himself. Caniff was the ultimate Goodwill Cartoonist Ambassador. I met collector Joe Goggin at the event, and within a year or so found out about Comic Fa! ndom, Pa flea markets (and Ted Hake!), Abe Paskow and others . 40 years ago seems like a long time, but also seems like a twinkle in a collectors eye.
