I inherited this skillet from my great, great aunt in Akron, OH. I received 2 Griswold slant EPU skillets and one labeled "The Favorite". All other skillets from Piqua Foundry that I've seen are labeled as so. Is this an early one or is it possible it could be from 1880-1888 when the foundry was still in Cincinnati? Any info would be helpful, see attached pics.
