If you buy the OE Honda bodywork, it comes with stickers pre applied. You can buy the stickers separatley, although not sure if the MC21 Rothmans are still avaliable.

Check out the Parts Manual on this site and see if you can order them from your local Honda dealer. I can still get MC28 Rothmans from my dealer in the UK, but there are diferences between the MC21 & MC28.

Good luck
