An incredibly rare if not unique set of seven original mounted photographs of h. Eyres anti skidding appliance c1903. The photographs are mounted on green & blue card in which the four green cards have a paper information label fixed to the rear, other than some spotting on the images which look like its on the glass negatives they are in good used condition. Approx 10 by 8 inches. Not sure what the photos are for but could have been used as a demo for the patent office in 1903 or a shop display but never seen another set or the actual skidding appliance.
