The Ponte Vecchio, the most curious bridge in the world, Florence, Italy
Stereographs are devices capable of building a three-dimensional image out of two photographs that have about two and a half inches difference between them so that it could imitate the two eyes’ real field of view. Combining these images into a single one with the help of stereoscope, a person can experience the illusion of the image’s depth. Stereoscope uses the same principle as in human binocular vision. Our eyes are separated by about two inches, so we see everything from two different angles. When the brain combined those views in a single picture, we get the spatial depth and dimension. Stereographs were extremely popular between 1850 and 1930 all around the world. Millions of stereographs were made during that time. There was a broad range of themes: landscape, travel, historical moments, nature disasters, architecture and many others.

Italian Time Travel Trip 1906 Italy was getting ready for the 1908 Summer Olympics when Mount Vesuvius erupted. It became active in January and culminated with an eruption on April 5th, when Vesuvius killed over 100 people and ejected the most lava ever recorded from a Vesuvian eruption ever. Government funds previously allocated for the Summer Olympics had to be diverted to the reconstruction of Naples, requiring a new location for the Olympics to be found. April 10 – The lava flow from Mount Vesuvius, which had almost ceased, starts again in the direction of Torre Annunziata; reached the cemetery of that town and then turned in the direction of Pompeii (again!). April 28 – The Milan International world's fair opens in Milan. It welcomed 4,012,776 visits and covered 100 hectares (250 acres). May 6 – The first Targa Florio, an open road endurance automobile race, starts in the mountains of Sicily near Palermo. The race was initiated by Vincenzo Florio and is considered to be the oldest sports car racing event.
