They have the two advert cards in the bottom corner... kinda ruins the looks of it.
Anyone know where to get a 'perfect' uncut with 56 rider-backs?
Buy two, cut them in half, put the two non-ad-card halves together and mount.
Either that or simply trim the ad-card row off, since you're only mounting the backs.
Normally I'd never suggest cutting an uncut sheet, but these are pretty inexpensive - less than some posters of that size.
