The holder comprising a grid and a pivotal retainer. The grid comprises a plurality of elongated rectangular shaped bars being aligned parallel to one another on an equal plane, spaced equally apart and supported by two elongated rectangular shaped crossbars. The retainer comprises a plurality of relatively thin elongated bars having uniform circular cross sections throughout their lengths. They are aligned parallel to one another on an equal plane, spaced equally apart and held in place by two crossbars located perpendicular to and at the ends of said retainer bars and are made of the same stock as said retainer bars. The retainer being supported at its back end by fitting the rear retainer crossbar in notches provided at the back end of a portion of the grid bars and being secured in the notches by two small spring wire retainers. The replaceable cover can be fitted to the cover holder by opening the retainer, placing the cover face up on top of the grid, aligning the main cover portions with their corresponding grid bars and aligning one of the cover's folded edges with the front of the grid, finally, by closing the retainer and extending the two L-shaped bars over the retainer's front crossbar the system is ready for use.
