The inner workings of a cuckoo clock are far more than a few cogs and gears. The mini-men have to begin the day with a shift mining into the wall for precious shavings to fuel the engine and then they have a shift doing the shovelling. If the worker has been good then they may be let out early, but should they not be so, they have to spend an hour cuckoo taming and grooming so it looks it's best on it's next outing. Drawn by hand with colouring pencils. Probably my current favourite in my gallery.
