This chalkboard art print isn't just adorable, it's instructional too. All the fixings for the drink served in a signature copper mug, the Moscow Mule, are illustrated in chalk, the dusty stuff used to color and shade each element and letter in the piece. The original chalk drawing lists the ingredients and how to prepare them to make the perfect Moscow Mule, complete with a mint sprig for garnish.
