Abstract
921,289. Picture and like frames. AGFA A.G. July 21, 1959 [Aug. 9, 1958], No. 2502159/. Class 11. [Also in GroupXX] A transparency mount comprises a front part A and a back part B fitting therein, both having apertures the same size as the image zone, the part A having a shallow recess on one side to accommodate the transparency only and the part B having a deeper recess on one side to accommodate the transparency and two protective plates, e.g. of glass or plastic material, so that by having one face or the other in contact with the part A, either the transparency alone or the transparency between protective plates can be held on the mount. The mount may be roughened where it engages the transparency and the part B is provided with a recess at one edge or corner for facilitating its removal from the part A.
