Coffee, besides helping us feel less rage in the morning, has become a great art medium. Now, artist Michael Aaron Williams has taken coffee art a bit further by going old-school — with a series of portraits painted on ledger paper that dates back to the 1920s and 30s.

The weathered paper adds the perfect backdrop to the brown, amber and copper hues of the coffee, while Williams’ partial portraits complete the antique feel. See more of Williams’ work at his Facebook page.
