1980's Allis Chalmers Collectible Prints 1938 UC and WC Tractors S53

This lot consists of 2 prints that were taken from some brochure or magazine by an avid collector in the past.  I found that at his estate sale and thought they were too nice to pass along to others.  The top print is of a 1938 Allis-Chalmers UC tractor.  The lower print is of an Allis WC but it doesn't give me a date.
