I have three racing banners for sale. They make a great addition to any racecar shop or garage. I don't have the exact diameters of them(will get them tonight) but they are HUGE.

1.Procharger banner- I think its the 72"x 37" banner.
2.NX nitrous express- Don't know the exact size, but it is much larger than the procharger banner.
3. Black Summit Racing banner- About the same size as the procharger.

Will get some pics tonight.
