While visiting an estate in Ontario's Niagara Falls two years ago, a film enthusiast stumbled upon a rare World War I Richard Verascope stereo camera previously owned by the French Army. Here's what he found inside.

The verascope camera, which was purchased by A Nerd's World's Chris Hughes, was found in pristine condition and included the original leather carrying case and glass slides. The antique had been in the possession of an elderly man who was clearing out his camera collection in preparation for retirement.

"Each slide is a piece of history in photographic form and I get shivers every time I place a glass slide into the 3D stereo viewer," writes Hughes.

Here's what a typical glass slide looks like:

And A Nerd World's 3D digital rendering:

This one's a bit harrowing. Two soldiers help a commrade who has been shot, while a dead body lies in the background:

This one is Hughes's favorite: Four friends looking straight into the lens:

About two dozen soldiers try to push a cannon to the top of a hill:

The scale of the destruction is clearly demonstrated in this photo:
