Abstract
Abstract A mount for display objects including drawings, paintings, thin sheets or other large thin sheets comprising a pair of opposed rectangular flexible plastic sheets arranged face to face and adapted to receive the display object therebetween, at least one of said sheets being transparent. Said sheets have continuous opposed peripheral inner wall portions with peripheral recesses formed in said wall portions defining a peripheral cavity. A sealant fills said cavity throughout 360° for securing and sealing together said sheets around their periphery. The space between said sheets is evacuated with the display object operatively, snugly and protectively held and sealed between said sheets. A continuous channel extends around and receives and encloses margins of said sheets overlying said sealant. Additional sealant substantially fills said channel and is interposed between said channel and peripheral outer sides and edges of said sheets.
