This is the classic war poster "Keep Calm and Carry On" reworded to "Keep Calm and Sail On". There's a silhouette of a sailing boat next to the words. It makes a great set of gifts or treats for sailing enthusiasts, boat owners, sailors, etc.
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.
