This is the classic war poster "Keep Calm and Carry On" still with the original crown at the top. It's reworded to "Keep Calm adn Proof Read". It's a funny design that makes perfect presents or gifts for teachers and students alike. Not to mention editors and writers, anyone who works with words. It's a great poster for your classroom, or study hall too.
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.
