Abstract: A tray and its method of formation for supporting card-like articles in juxtaposed relation therein comprising a one-piece body of plastic material molded in flat form with a base, a pair of opposite side parts and a pair of opposite end parts. The side parts and end parts are joined to the base by fold lines about which the parts can be upfolded to form side walls and end walls for the tray. The end walls have tabs at their lateral edges and the side walls are formed with slots which receive the tabs when the walls are in upfolded condition. The end walls form an angle with the vertical in the secured position and the lateral edges are engaged between pairs of ribs formed on the side walls.
