Offered here is a vintage "Just Bubbling Over" 3D Color STEREOSCOPE CARD. Published in 1899 by T.W. Ingersoll, this turn-of-the-century card is in great shape! Photos adhered to thick cardboard, there is the typical slight bow to the card, along with some minimal wear such as rubbing (mostly along the edges) and minor spotting. Extensive text on back of card. The card measures 7" x 3.5".

A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image. A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one "stereo window".
