Ever heard of George Nelson? When it comes to clocks of the period, he stands above the rest. He made clocks that looked like sunbursts, others whose hands pointed to colored balls on thin pins, and even others that resembled human eyes with the hour and minute hands stemming from the center of the iris. A number of other clock makers imitated his works, including Elgin, Lux, Westclox and Seth Thomas. You'll probably pay about $400 for an original George Nelson today, but could pay as little as $10 for one of the imitations.
