Without going into the why of it.. there is a company on line who will print you a 3x4 ft banner for just over 20 usd delivered in the usa. You can get several lines of large print. Fewer lines larger print. Why would you want one? They make great winshield covers to keep the sun out.. (legal when you park your car anywhere even the mall parking lot) You get almost free advertising just put your company name ... website... phone number and I like to put my price on it so people will have a reason to look on the web site. This is gorilla marketing definitely not for the upscale photographer. But a very low cost and I assure you fairly effective advertising method for the mid to lower end customers that everyone else loves to hate.
