Shield style clocks are among the first cuckoo clocks produced in the Black Forest. The clocks date back as far as 1750. Uniquely hand painted these clocks once rode on the backs of clock peddlers and their huge backpacks. Today shield style cuckoo clocks continue to be built and hand painted by talented artisans.
