Yes, and on this planet it's STILL an 'S'...
I'm always open to requests, and when a very nice man from California asked me if I could make a Superman coaster with the logo on a blue background my answer was, of course, 'yes'.
A Superman coaster was, if you look back in my library, one of the first real multicoloured designs I made. Since I like going back and updating old designs I decided with this one to alter it just a wee bit; Instead of just the red and yellow I also made an under-piece in black with 1mm lines standing proud of the surface, which gives a thin black outline around the borders of the colours.
The very nice man from California was very happy with it, and hopefully you will be too! If you'd like one but don't want to print it you're welcome to order from my Etsy store - www.etsy.com/uk/shop/enterprisexddesign
