like them both...kinda agree with the transparent background though..

my car ones are usually just the lettering, each letter being separate so you just have "www.wiltshirebikers.co.uk" in lettering to stick somewhere.

might be a good idea to get whatever we do get in a couple of colours? black and white? just thinking if people wanted to stick on black paint, black lettering would be pointless..similarly white on a silver bike wouldn't look good
