An improved frame construction enabling front mounting of articles and providing a rear mounting effect. The frame is of plastic composition and has a well and border members. The well includes a smooth front panel and a groove is formed coplanar with the front panel within the frame. The picture overlies the smooth front panel and there is overlying the picture a transparent non-marring and non-discoloring plastic sheet which is completely transparent. A mat having a pressure-sensitive adhesive at the outer periphery seals the transparent sheet cover to the picture and the outer periphery fits within the groove and adhesively secures the picture at its outer periphery to the frame with the outermost edges of the mat being located within the groove. The picture is totally sealed and once the picture is mounted it provides the effect of a rear mounted picture, with mortised grooves located diagonally at each of the corners of the border members, enhancing the effect of a rear mounted picture.
