This is the classic war poster "Keep Calm and Carry On" reworded to "Keep Calm and Party On". There are silhouettes of cocktail glasses sitting on the words, with sparklers, and stars in the background. It's a happy fun design that makes beautiful gifts, party invitations or decorations.
I've put this on a purple background, but you can change this really easily. Hit 'Customize it' and then 'edit', and you'll be able to change to absolutely ANY color you prefer.
