2025 Half Century of Progress Collector's Edition

The 2025 Half Century of Progress Collector's Book features profiles and action shots of the hard-working machines that broke the plains to make agriculture our most important industry in the United States. The book is produced by the hard-working volunteers that host the show. You will see vintage tractors plowing, corn pickers picking corn, and soybean harvesting. The book also includes articles covering the many happenings of the show. 

The Half Century of Progress Show is held every other year at the Rantoul Air Base near Rantoul, Illinois, and is the world’s largest tractor show featuring working machinery.
