I've attached a HUGE png file that Ken used for the vinyl shop. It's got some jaggies from the vectorization of the font, but will be good from afar, especially if you're making them at home for cheap. I keep wanting to make a few variations that are nice and clean for different applications. Forthcoming hopefully.
I've also attached the vector file for illustrator which has a few little elements you can use if you have that software. If you're interested the font we're using is called 'dear joe four'. A demo of it can be found at various free font sites.
