The first Maduro cigar I smoked was a Motor City, and yeah, they were from Detroit, it looked as if it had been marinated in used motor oil, but was a good smoke. No dye or stain from the cigar. Pretty sure the painting, staining of the cigars may've come into fashion at the time of the cigar boom.Smoked that Motor City around 1952-1955. As I recall it was described at the time as "a dark cigar."
