Here's something I came up with while working on another anchor/nautical themed print. As you can see it's based off the famous "Keep Calm and Carry On" poster from the WWII, which if I may say is quite frankly an excellent design. Simple, bold, and gets the point across. I'm not suprised that so many people make use of it and it's public domain status.
Below you will find a couple different worn out variations.
