Advertise outside of your store front with this sidewalk sign holder. The hinged aluminum frame is lightweight yet sturdy and folds flat for easy portability and storage. Posters measuring 24" x 36" (W x H) can be inserted into a slot on the top of the sign holder while the clear plastic cover and backing hold the insert in place. Rubber feet prevent sliding. Passing customers can conveniently view messages from two sides of this double-sided sidewalk sign holder.
