I have a marshall sticker on my back window......... you can't really see it becasue it is tinted?!?!? I don't mind it actually but would object to an A4 sheet!
I also got given Marshall key rings and tax disc holders (2 strangely). The way I see it is my main key goes on my key ring and the spare may as well have a free key ring rather than me paying for something I'll never use!
