Abstract
A visible file-card system including a holder and a plurality of cards with cooperating means for pivotally mounting the cards in the holder in superimposed, overlapping, stepped relationship with a portion of the face of each card adjacent its lower edge, visibly exposed. The specific structure for mounting each card on the holder comprises a resilient pivot strip secured to a tab at the upper edge of each card having pivot extensions or pivot lugs on its ends. The holder comprises a back with a longitudinal channel or elongated recess which has flanges at its edges provided with pairs of horizontally spaced opposed pivot openings for receiving the oppositely-projecting pivot lugs of the pivot strips, as the strips are contracted by bending and then allowed to expand to project the pivot lugs into a pair of the opposed pivot openings.
