I'm not sure why I do not own this one, but somehow I either missed it or didn't have the money. Either way, someone has an awesome specimen of the 1904 World's Fair padlock.
This padlock had a high bid of $400 (Plus $3.77 Shipping).Manufactured by the Eagle Lock Company, Terryville CT. Lock is in extremely good condition, with fine details clearly visible on each side. Lock is still functional. - eBay (23 Sept 2013)
