Llewellyn runs for high office and almost gets it, much to his horror. Ozy expands. Millie introduces her presidential sock puppet.

Finally, I do sell the original art from O&M strips--$100 apiece, with very few exceptions made (for some of the more popular strips). The art is bigger than you'd think--the sheets of paper I draw them on are 17 inches by 6 1/2 inches. If you're interested, feel free to e-mail me.
