1936 Caterpillar 4-5 Plow Diesel RD4 Vintage Ad - Barnyard Patina N167

This original 8.5 x 11" magazine ad was neat the back of the magazine and exhibits classic barnyard patina.  Not bad enough to toss, but not pristine either.  The ad features the Caterpillar Diesel RD4 tracked tractor from 1944.
