Received the stereoscopic machine today, it's in perfect condition. 250 stereoscopic photos from 1915 in the Bahia Blanca/Sierra de la Ventanas region!

dat glass aint cheap
Weird, if Cappellin close his factory in 1931, this piece of glass can't be from the 1950s (the signature looks fine but I know better ceramics/porcelains than glass).
Found those 36 glasses attributed to Vittorio Zechin (was the art designer for Cappellin & Venini it seems), sold for 1.400 euros in an auction
Always funny to buy something with an intuition, he he
