“The Bucyrus Brewing and Furniture City Brewing cards of the M101-4 set are known only in uncut sheet format (one Bacyrus and two Furniture City sheets). They are blank-backed with the sponsor label printed in the sheet border on front. In addition, a single uncut sheet of the M101-5 set, sponsored by the Chicago Examiner newspaper, was discovered in September 2010.”
