This is the classic war poster "Keep Calm and Carry On" reworded to "Keep Calm and Milk On". I've kept the crown at the top, and added the silhouette of a cow beside the letters. Makes beautiful presents or treats for people who love cows, or farmers, or butchers, or people who love milk, or milkmen/milkman/milkperson, those kinds of people.
I've put this on a blue background, but you can change that really easily. Hit 'Customize it' and then 'edit', and you'll be able to change to absolutely ANY color you prefer.
