Containers are mounted in rows on a display rack having shelves inclined upwardly so that articles on the shelf tend to slide forwardly. The containers arranged in rows located side by side across the width of the shelf are formed of board or as transparent plastic jars. Each container has a base on the shelf, upstanding front and rear walls and upstanding side walls with the front and rear walls inclined at a wall angle to a plane at right angles to the base the base so that with the base sitting on the inclined shelf the front and rear walls stand substantially upright. The front wall is higher than the rear wall to provide an exposed strip of each container of the row so that all strips can be seen in front elevation. The strip can be marked with a bar code.
