Abstract: Apparatus for supporting a multiplicity of cards of the type having a pair of parallel T-shaped slots formed along one edge thereof, each of which defines a pair of opposed flexible edge tabs. The apparatus comprises a unitary structure molded of plastic material which is arranged to be supported on a horizontal surface. The structure includes front and rear card supporting walls spaced apart to receive the cards therebetween in row formation, a pair of transversely spaced card supporting walls extending between the lower portions of said front and rear walls for supporting the entire row of cards along the portions of the slotted edges thereof extending outwardly from the T-shaped slots therein, and a rail of T-shaped cross-section extending vertically upwardly along the inner portion of each of the transversely spaced walls between the front and rear walls for engaging the slot defining edges of the cards.
