Just to be on the safe side I'm checking on the legality of using the Buick name on a banner that is being sold. As soon as I know, I'll let everyone here know. Wouldn't want to get sued by cash strapped GM you know.(although you can't get blood from a turnip.....)
As far as cost, the price for one of these would be around $55 plus roughly 7$ for shipping via UPS. It's on 13oz vinyl with brass grommets. It's printed at 370 DPI from a grandformat printer and I could do somewhere around 5 at a time. I'll have to pay the place I work at for them, so I won't really be making anything on them as they are usually getting around 65 plus shipping for a 3'x12' banner. I'll be able to get them to sell at 55 though.
