hoefler, I had this printed at Fastsigns and the graphic was found online. You can find a free graphic or use sites that sell images, but you must find one that is large enough to fit the size without getting distorted. I printed the vinyl about an inch larger top to bottom and side to side and trimmed to fit.
BTW, as a graphic design company I have access to custom printed, adhesive-backed perforated vinyl, meant for exterior window advertising... if anyone would like pricing I can get it for you. This would not include any installation, just the actual printed product.
Hi Dennis, I'm a graphic designer and have my own company. I have not personally purchased or installed the product but can give you an estimate for what the perforated material (printed with your design) would cost, using my supplier: about $5 a square foot, plus UPS shipping. You can PM me for more details.
