An A-frame stand for supporting display boards is made from a pair of like, inverted, generally V-shaped end members and a pair of rigid cross pieces that extend between the end members to maintain them in spaced, vertical planes, and in registry with each other. A pair of board supporting tracks are adjustably mounted by a plurality of hanger elements to one or to both sides of the A-frame stand to extend between the end members in vertically-spaced, parallel relation to each other. Each hanger is in the form of a metal strap secured intermediate its ends to one side of a track at one end thereof, with opposite ends of the strap extending around a leg of an end member and being releasably secured together so as to allow vertical adjustment of each track on the stand. Each track has at least two longitudinally extending recesses or grooves in both its upper and lower surfaces for slidably accommodating one edge of a display board.
