Ok here goes with the artwork.
Supplied image from Terry -

Clubman artwork -

(yes it is crappy, i have the EPS to make the stickers from)
I think the top right hand side of the flag needs rounding off, hard to see in the original image a second pic from someone would help a lot if this is the case, along with the removal of the black in the centre of the C.
This should print the correct size when printed at 100%.
Can some one (or a couple) of people print it and compare it to an original

Once I have the ok i'll sent it to the printer and see if we can get a prototype made, i should have some pricings by then also.
Cheers,
Andrew
