This vintage porcelain CF & I Coals sign reads: “C.F. & I. Coals / Produced by the Colorado Fuel and Iron Company / Sold Here.” “C.F. & I. Coals” is in red lettering, and beneath this text there are three identical bearded men or devils in red robes (appear to be running), each carrying a black bucket of coal with the word “coal” written on the buckets in white lettering.
