A stereoscopic display system ( 10 ) comprising a pair of convergent lenses ( 14 ) and a sheet of resilient, transparent material ( 12 ) formed into a picture holder ( 18 ) and a lens holder ( 20 ) joined by a base ( 16 ) that holds them erect and parallel for viewing a stereoscopic image pair mounted in the picture holder through the lenses mounted in the lens holder. A median slot ( 21 ) extending through the lens holder into an adjacent portion of the base divides these sections into two lens support arms ( 31 ) and provides an intervening space shaped to accommodate the viewer's nose and to maintain a clearance space for the resilient approximation of the lens support arms. Adjustments for focus, diopter, interpupillary distance, and stereofield separation and vertical alignment, are made by flexing the lens support arms collectively and differentially in longitudinal and transverse directions. The picture holder is adapted to durably or transiently hold stereograms of various sizes and formats, in the form of prints, transparencies or slides, LCDs or other thin image support media. A second picture can be displayed on the reverse side of the picture holder. The lens holder can accept replacement optics for optics for customization to the user's vision requirements and can be adapted for durable setting of interocular distance.
