Original unsigned pencil sketch of Linus eating a sandwich, with Schulz writing in the balloon above him, 'My great-great-great-great grandmother used to make bread that was as good as Butternut, but, of course I haven't seen her in years,' on an off-white 4 x 6 sheet. In fine condition. This drawing was originally done for an advertising agency in San Francisco around 1970, which handled an account for Butter Nut Bread, and was acquired from an agency employee.
