(Walt Disney Studios, 1940) Mimeographed typed memo for the Disney cartoon "Goofy's Glider," headed "Story Gag Outline, (Return to Leo Thiele 2-C-8), April 23, 1940," four pages, 8.5 x 11, describing the concept for a cartoon in which Goofy attempts to master a glider under the observation of a buzzard. The interesting outline offers ideas for flying-related gags ("When he finally gets aloft he has all kinds of experiences with a flock of geese…air pockets - bumpy air - low ceilings - twisters - big and little clouds - rain…he may be gliding upside down and not know it"), poses conceptual questions for filling out the short ("What funny take-offs can you suggest for Goofy?…How could the clouds work together to outwit Goofy?…In what funny ways could the Buzzard keep tab on Goofy as a running gag throughout the picture?"), and has a one-page copy of concept artwork for the cartoon. The memo requests that any ideas be submitted to Leo Thiele, a writer and layout artist in Disney's animation department. Many of the elements and ideas described in this memo made it into the final cartoon, which was the first of the 'How To' Goofy shorts. In very good to fine condition, with edge toning and some old tape stains to one page.
