Included in this lot is a vintage 'Borax is King 20 Mule Team Package Soap' tin sign. Teams of mules were used to move millions of pounds of Borax from remote mines in inaccessible Death Valley to the railroad at Mojave. Originally, teams of eight and ten mules were used, but the trek proved too much. A man named Ed Stiles came up with the idea of hitching two 10-mule teams together—twice the normal amount—resulting in a 100-foot-long team that took 10 days to carry 10 tons of borax one way across the desert. In 1894, a steam engine named “Dinah” was brought in to replace the mules, but Dinah was no match for the epic 20 mule team’s power. She broke down and was towed back to town by the very mules she tried to replace. The power of Borax works just as hard as the heritage of its mule team, cleaning deep to tackle your toughest mess. The sign is in fair condition and shows some damage, rust, and scratches. There is a wooden board screwed to the back side of the sign. The sign measures 23 3/4" by 35".
