Abstract
Abstract This invention is a shopping cart display guide selector for attachment to the handle of a shopping cart. The display guide selector has an outer cylinder clamped to the handle of the shopping cart. An inner cylinder is rotatably carried therein. A knob allows a shopper to turn the inner cylinder to any given position. On the inner cylinder is attached a sheet of paper containing information such as the store specials. A magnifying viewing window is contained in the outer cylinder so that a shopper may easily read information contained on the paper. By removal of a pin, the inner cylinder may be removed and the paper replaced to give other information. Friction between the inner cylinder and outer cylinder maintains the inner cylinder in any position to which it may be rotated by the shopper.
