LEHIGH VALLEY, Pa. – Mack Trucks has unveiled the Mack Centennial Trailer Exhibit as part of its year-long centennial anniversary celebration.

The exhibit is a mobile museum that integrates custom videos, photography, and Internet-based content. The trailer, decorated with a 53-foot image of a bulldog blowing out candles on a birthday cake, will serve to tell visitors the story of the “Bulldog-tough” Mack truck, and its role in the history of the 20th century.

A new Vision highway tractor will haul the exhibit.

“A walk through this exhibit will give visitors a real sense of the way Mack has changed with the needs of its customers and society over the last hundred years – as we continue to change today,” said Mack president and CEO Michel Gigou.

The exhibit starts with the story of the Mack brothers, who founded the company, and ends with a look at today’s Mack products. The trailer also demonstrates how trucking has changed over the last century, and the important role trucks have played in major construction projects like the Hoover Dam and New York City subway system.

After being introduced at several Mack facilities in February, the exhibit will be open to the public from Feb. 21-24 at the “World of Concrete 2000” truck show in Orlando, Fla., and will then go on the road to exhibits across the country.
