This is the classic war poster "Keep Calm and Carry On" reworded to "Keep Calm and Lawyer Up". I've kept the traditional crown at the top, and added a pair of handcuffs next to the words. This is not necessarily good advice for war time, but it is great advice no matter what you've been arrested for. Or think you might be arrested for. Makes great, funny presents for lawyers or anyone in the legal system.
I've put this on a purple 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.
