I haven't been able to verify any of the details, but a post on the Internet, states that the photograph was taken in 1964 by LA Herald Examiner photographer Doug Wilson at Disneyland, during an event for the Foundation for the Junior Blind.
Apparently, Lyndon Johnson bought a print for the White House. I would love a print, too, but can't find one for sale anywhere. (Sad side note: The photographer, Doug Wilson, rode his motorcycle off a cliff and died not long after the photo was taken.)
