A display wall for a product display system, said system incorporating shelving brackets or similar items, said shelving brackets or similar items having a male anchor portion with a profile which is an upwardly curved tab of substantially even thickness that is adapted to be received by an anchoring cavity, said wall being comprised of: a plurality of interconnectable and int-erlockable panels (71, 75), each said panel (71, 75) having anterior and posterior surfaces and having upper and lower edge surfaces; each panel having upper (72, 73) and lower coupling projections integrally formed in said panels, each (72, 73, 77) extending from a posterior position at or near an upper and lower traverse edge of the panel (71, 75), respectively; wherein said projections (72, 73, 77) provide a complementary tongue and groove arrangement for assembly of a plurality of said panels (71, 75) into an upright wall; and wherein the upper coupling projection (72, 73) has a first surface that extends from the upper traverse edge in a posterior direction and an upward manner away from an anterior surface of the panel, the lower coupling projection has a second surface that extends from the lower traverse edge in a posterior direction and an upward manner away from the anterior surface of the panel, the first and second surfaces defining an anchoring cavity in an assembled state of two interconnected and interlocked panels (71, 75), the anchoring cavity featuring a curved profile consisting of an upward curve away from said anterior surface of the panels, the cavity being of even height, and in which can be received and which can be filled by said male anchor portion of said shelving brackets or similar items, the curved profile further being of constant radius of curvature and extending through a circular segment of 90° characterised in that the upper coupling projection (72, 73) includes, in profile, one inner and one outer upwardly curved male tang sharing substantially the same centre of curvature; the lower coupling projection includes, in profile, a female cavity adapted to receive said inner tang; and the outer tang is adapted to make engagement with an outer surface of an identical lower coupling projection. a plurality of interconnectable and int-erlockable panels (71, 75), each said panel (71, 75) having anterior and posterior surfaces and having upper and lower edge surfaces; each panel having upper (72, 73) and lower coupling projections integrally formed in said panels, each (72, 73, 77) extending from a posterior position at or near an upper and lower traverse edge of the panel (71, 75), respectively; wherein said projections (72, 73, 77) provide a complementary tongue and groove arrangement for assembly of a plurality of said panels (71, 75) into an upright wall; and wherein the upper coupling projection (72, 73) has a first surface that extends from the upper traverse edge in a posterior direction and an upward manner away from an anterior surface of the panel, the lower coupling projection has a second surface that extends from the lower traverse edge in a posterior direction and an upward manner away from the anterior surface of the panel, the first and second surfaces defining an anchoring cavity in an assembled state of two interconnected and interlocked panels (71, 75), the anchoring cavity featuring a curved profile consisting of an upward curve away from said anterior surface of the panels, the cavity being of even height, and in which can be received and which can be filled by said male anchor portion of said shelving brackets or similar items, the curved profile further being of constant radius of curvature and extending through a circular segment of 90° characterised in that the upper coupling projection (72, 73) includes, in profile, one inner and one outer upwardly curved male tang sharing substantially the same centre of curvature; the lower coupling projection includes, in profile, a female cavity adapted to receive said inner tang; and the outer tang is adapted to make engagement with an outer surface of an identical lower coupling projection.
