This is one of the earliest designs I offered when we started doing vinyl decals. In my files, it's listed as item #0035.
Totally clip art. When we bought the cutter, we also bought this book of vector clip art specifically designed for cutters. http://amzn.com/B003YM6HYY It's marketed to sign making companies so it's always amusing when I see signs that use clip art from this book.
If you have a cutter, and you are just starting out, I highly recommend getting all three books. It gives you a great inventory of designs to start with, without having to go online and rip off someone else's art.
If you don't have a cutter, and would like this dragon decal, we have it in our Etsy shop. https://www.etsy.com/listing/160625.....tablet-sticker
