From an Archive Room at Nela Park in Cleveland the writer also had access to 20 negatives of individual Hammer lamps. A photograph was taken of each negative, in the sunlight, with the background being the noon day cloudless sky; this was accomplished with a Sony MVC-FD81 Digital Mavica camera. Then a "positive" was obtained through use of a scanner and Adobe PhotoDeluxe 2.0. These images are also shown below. Although the results leave much to be desired, the writer felt that the viewer might appreciate seeing a "close-up" of individual Hammer lamps, as originally displayed.
