A spring loaded holder with a holder plate which is rotatable between a deactivated zone and an activated zone. When the holder plate is manually moved to the activated zone a cam action will be activated to apply a holding force to the holder plate for firmly holding objects of varied thickness. Such holders can be installed in a picture frame for holding a stack of art sheets. For a vertically mounted art frame a displayed art sheet smaller than the internal size of the art frame can also be held by this holder without shifting. Unused art sheets and associated mat boards can be mounted along with the displayed art sheet. Since all art sheets and mat boards are kept together, the change of art sheet display can be easily achieved any time if desired. Such picture frame can also be used for displaying and storing expired calendar books. The holder can be further modified and used in a variety of holding boards including fun boards, bulletin boards and poster boards. It is proposed that an ensemble including an art frame of the present invention and a mat board of standard size and a plurality of art sheets standardized to match the art frame and the mat board be sellable in one business transaction or one pseudo business transaction.
