I recently stumbled across the Holy Grail of cast iron cookware: an Erie #8 Spider skillet. According to the Wagner & Griswold Society, the Erie spider pan was produced between 1890 and 1891 before it was pulled from production. The spider logo was borrowed from Robert the Bruce, the Scottish king who fought to free Scotland from English rule. Griswold internal company communications were headed with the words “As the little spider brought success to Robert Bruce, so cooking utensils bearing this trademark brings success to all who use them.”
