ABSTRACT:
A slide mount for a transparency has a generally rectangular and annular back frame formed with front and back faces terminating outwardly at four straight outer sides, a central window, an annular row of mounting studs projecting from the front face around the window inward of the outer sides so that perforations in the transparency fit over the studs with the slide spanned across the window, and an L-shaped lip extending along two of the outer sides and having an overhanging edge. The other two sides of the back frame are plain. A generally rectangular and annular front frame geometrically similar to the back frame is formed with front and back faces terminating outwardly at four outer sides, a central window, an annular row of recesses in the respective back face around the respective window inward of the respective outer sides, and an L-shaped lip extending along two of the respective outer sides and having an overhanging edge. The other two respective sides are plain. Each recess is elongated and extends parallel to a direction itself extending diagonally of the front frame. The lips, studs, recesses, and sides are so positioned and dimensioned that the front and back frames can fit together with the studs engaged in the recesses, the windows aligned, a transparency engaged over the studs gripped between the front faces, and the plain sides of each frame engaged under the overhanging lip of the other frame.
