1957 Porsche Diesel Tractor Ad Belvedere, IL Ad #1259

This original 5 x 6" magazine ad comes untrimmed from its larger 10 x 13" page and features a Porsche Diesel P133 tractor as sold through LO Shaw of Belvedere, IL in 1957.  This is the ONLY Porsche tractor ad I've come across in the past several years.
