• said shoulders of said case defining a width therebetween, said side edges of said panel defining a width therebetween, said width between said side edges of said panel being less than said width between said shoulders of said case;
• said upper side flanges of said panel defining a width therebetween, said width between said upper side flanges of said panel being greater than said width of between said shoulders of said case;
• said panel having a generally lower flange at said bottom edge, said lower flange of said panel having a pair of opposite ends and a pair of sides extending between said ends of said lower flange of said panel;
• said lower flange of said panel lying in a plane extending substantially perpendicular to said front and back faces of said panel;
• one of said ends of said lower flange being outwardly extended from one of said side edges of said panel, the other end of said lower flange being extended from the other side edge of said panel;
• one of said sides of said lower flange being outwardly extended from said front face of said panel, the other side of said lower flange being outwardly extended from said back face of said panel;
• the one end of said lower flange and one of said side edges of said case lying in a common plane with one another, the other end of said lower flange and the other side edge of said case lying in a common plane with one another;
• said side of said lower flange outwardly extending from said back face of said panel and said back face of said case lying in a common plane with one another;
• said side of said lower flange outwardly extending from said front face of said panel being outwardly extended from a plane in which said front face of said case lies;
• said side of said lower flange outwardly extending from said front face of said panel being positioned beneath the bottom edge of the wall hanging;
• said panel being slidable in said elongate slot of said case between a retracted position and an extended position;
• said lower flange being positioned adjacent said lower edge of said case when said panel is positioned in said retracted position such that said lower flange abuts said lower edge of said case;
• said lower flange being spaced apart from said lower edge of said case when said panel is positioned in said extended position such that a portion of said panel adjacent said bottom edge of said panel extends below the bottom edge of the wall hanging, said upper side flanges of said panel abutting said shoulders of said case when said panel is positioned in said extended position;
