Don't miss this chance to own the 19th century version of Netflix! When special cards are placed in this stereo viewer, they are transformed from double images to 3-dimensional pictures! The stereo viewer measures 13” front to back and has a 5” handle. A dozen cards featuring shots from Philadelphia’s Centennial Exhibition in 1876 are included. The smaller cards measure 6 ½” w by 3 ¼” l, while the larger ones measure 6 ¾” w x 4” l. A great conversation piece!
