This brochure is nicely illustrated and has lots of detailed information on the features and benefits of these Rumely DoAll Tractors.  The back cover panel is printed with document code “AD 1122-1927” which we take to indicate a 1927 publication date.   This vintage original brochure is fully complete and intact with just light handling wear.   Overall condition is excellent.
