internal side of the bridging member to function as the receiving channel for the elongated gripping clip.
The invention also comprises a method of exchangably gripping and releasably supporting a sheet-like poster for display purposes by a gripper assembly comprising the steps of: arranging a first elongated extruded gripper clip in an elongated slot of an elongated extruded receiving shell, the elongated gripper clip being pre-loaded with a first sheet-like poster therein; removing the pre-loaded elongated extruded gripper clip from the elongated extruded receiving shell; and inserting a second elongated extruded gripper clip in the elongated slot of the elongated extruded receiving shell, the second elongated gripper clip being pre-loaded with a further sheet-like poster therein for display of further poster in place of the first sheet-like poster.

Associate professor Mark Muñiz says it would fit with a theory that people lived along the edge of glaciers as they receded. It challenges previous beliefs that glacier-caused flooding in northern Minnesota caused the earliest humans to inhabit the south.
