Been doing some experiments with electrolytic etching of brass, and this is my firest semi-successful test. Some of the toner came off in the process. hence the low quality of the image and the large blank spots, but I was mostly doing it to see how well it could come out, and aside from the flaws, I think it came out rather well.

The image I used was from an old post card I have showing the Waltham watch company factory and some of their movements. Can't really see the factory but you can make out the trees and one of the watch movements.
