So you want something big, that folks can read from a distance.  Kind of like a billboard -- only it needs to go up and down quickly.  And you want to change out the message on a regular basis without spending your entire marketing budget for the year. Impossible?  Nope. What you need is an inflatable wall.  This one is 5’W x 15’H x 10’W. Lightweight wrinkle-resistant mesh banners are attached to both sides with Velcro. It’s a really great solution when you need big outdoor signage in a hurry.
