It's the Great Pumpkin, Charlie Brown (1966)|
Production cel of Charlie Brown, Pigpen and Lucy Van Pelt.
A fantastic cel of the gang dressed in their Halloween costumes-- They're downright spooktacular! And poor Charlie, his attempt at trick or treating seems unlucky as he keeps getting those darn rocks.
This scene appears around the 13:17 mark.
Cel is slightly wavy, which is common for artwork of this vintage. A few tiny specks of line wear and paint from another cel adhering to the top. Barely noticeable.
The size of this piece is 12 Field (11"x13") and the size of the image is 7" h x 4" w.
