Some type of flexible wire is covered in orange and/or blue fabric to represent the official Fair colors. The fabric is entwined somewhat like a knot but with an opening at the center so that the ends of the scout bandanna can be pulled through. Mounted at the front with a post and threaded cap, is the die-cut brass Trylon and Perisphere symbol. Tiniest wear but clean and Exc. We've seen numerous bandannas but this is the only slide we've seen or know of. Rare.
