This is a scan of a negative from a Kodak 2D 5x7 View camera using a large "toy" Mirroscope projector lens from about 1915 made by the Buckeye Stereopticon Co Cleveland, OH. It is 2 thin 40mm wide back-to back single meniscus lenses with convex faces pointing outwards. Like a Periskop lens, changing the distance between lenses changes the image size. This is with an aperture disc in the center of about f5 and focal length around 12 inches. Cars were lining up for the monthly Cool Cruisin' Night in Princeton, WV where cruising is legal and they actually block the street off from regular traffic to accomodate the cruisers. It got crowded quick!
