Vintage 4 New NOS W.T. Rogers Yellow Plastic 3x5 Index Card File Case Box Office

All 4 are included in the sale. These are new and unused and I think they are from sometime in the late 80's or early 90's, can't be sure. The original clearance tags are still attached for reference. They are like hard shell plastic case. Each is 5.25x3x3.5 and meant for the 3.5 index cards.
