A display apparatus comprising: an indicia carrying substrate support means (81) and a backing means (83), the indicia carrying substrate support means including: a) a quadrilateral shaped frame of top, sides and bottom perimeter members to define a border about the indicia carrying substrate to be carried by the indicia carrying substrate support means, the frame presenting a clamping rim (10) (continuous or not) parallel to the plane of the frame; b) at least one substantially rigid clamping sheet (9), biased by at least one biasing means (8) of the indicia carrying substrate support means towards the clamping rim yet allowing the clamping sheet to be pressed away from at least part of the clamping rim in a direction opposite to the direction of bias, wherein part of the indicia carrying substrate can be selectively captured between the clamping sheet and the clamping rim to become retained with the display apparatus. The indicia carrying substrate support means is hinged with the backing means to be rotatable relative to the backing means and movable between a first position and a second position. The backing means includes a means to hold (80) which when the indicia carrying substrate support means and the backing means are in the first position, hold the clamping sheet relative to the clamping rim to thereby prevent the movement of the clamping sheet in the direction opposite to the direction of bias, and when the indicia carrying substrate support means and the backing means are in the second position, being a position where the indicia carrying substrate support means and backing means are rotated away from each other, the means to hold is released from holding the clamping sheet.
