This product is a vintage stereoscopic card featuring the image of "The Three Brothers" rock formation in Yosemite Valley, California. Produced by Bierstadt, the black and white image is printed on cardboard and is an original print. The stereoview card is a single piece and is not signed. It was produced before 1930 and is considered an antique. The card is listed by a dealer or reseller and is a part of the travel theme.  I am offering other vintage images and always willing to combine shipping when possible. Please request invoice from seller to combine shipping. Thank you for Viewing and happy Bidding.
