A system for attaching a plurality of folding cartons having images printed thereon is disclosed. An anchor folding carton may be secured to a wall and all other adjacent folding cartons may be secured to the anchor folding carton. In particular, the folding cartons may be attached to each other with magnets. Also, the top and bottom flaps and side panels may have angled reliefs that allow the adjacent folding cartons to lay flat on the wall regardless of deformations (e.g. curvature) of the paper used to make the folding carton.
