This is one of 6 designs I drew up for a contest, which is already over, so don't try to steal it...
The game is called Pirates, which has several sets, Cursed Seas will be the newest, and if any of my designs wins, you'll be seeing them in the sets. I did come up with backgrounds for 4 of them, and they are on the templates themselves.
It was hand drawn then colored with a mouse in oC.
