Picture display and mounting

A method of mounting a picture upon a display surface, the method comprising the steps of:

• providing a mounting comprising:
• a support substrate having a display panel which has a display surface on its front face, the display panel having a perimeter defined by a frame having a plurality of spars;
• each spar being made of leaves created from the support substrate and extending from the perimeter of the display panel, each of the leaves configured to be folded at least twice, in a rearward direction to create a spar having a polygonal cross-section;
• each spar having an attachment region located on a surface of one of the leaves and configured to attach to the picture at each respective spar;
• the spars being mutually interlocking behind the front surface of the display panel thereby to create the frame and to tension the picture,
• wherein the leaves include mutually engageable elements which, upon folding in the rearward direction, create mutual interlocking of the spars, and
• wherein the mutually engageable elements provide a cam action to draw at least two of the spars into location against a rearward facing surface of the display panel
• aligning the picture and the leaves by bringing alignment surfaces on the leaves into register with adjacent edges of the picture;
• with the picture and leaves in mutual alignment, attaching the picture to the leaves;
• subsequent to attachment of the picture to the leaves, folding the leaves rearwardly of the display surface, to create spars having a polygonal cross section;
• and
• mutually interlocking the spars.
