A whimsical poster realized ca. 1920 by John Onwy for the Toblerone brand of chocolate. Toblerone is a brand owned by Kraft Foods, who acquired the product from former owner Suchard in 1990. It is well known for its distinctive prism shape. In the picture the little girl is fixing herself a hearty dose of cocoa powder which comes, as the caption tells us, in bags with a lead seal on!
