I spotted this vinyl banner in Old Quebec, which with it’s historical building requirements can make signage a challenge. What this museum did was mount the banner between two bars on the face of the building. It looked like a pair of heavy duty towel racks!
It’s important to use vinyl banner material that will stand up to the blowing wind in cold weather. Normal vinyl will shatter like glass at temperatures below zero, a real problem in cold weather locations! We use a banner vinyl that’s good to 20 degrees below zero, part of our heritage of making vinyl banners for the ski areas here in New Hampshire.
