An elongated poster support arrangement comprising an elongated extrusion having an uppermost wall, a first tapered sidewall and a second tapered sidewall. The first and second sidewalls angularly extend from the uppermost wall. A central support wall is arranged between the first and the second tapered sidewalls to define a first longitudinal chamber between the first tapered sidewall and the central support wall and also to define a second longitudinal chamber between the second tapered sidewall and the central support wall. An arrangement of gripping members is loosely disposed within the second longitudinal chamber. The second chamber is arranged to receive a poster therein for pinched securement between the gripping members and the central support wall.
