Modern Treads: The Discount Tire Poster Collection
This new exhibit, debuting at the Phoenix Art Museum, will display more than a dozen oversized posters from Discount Tire’s collection, dating from 1900 to 1930.
“Discount Tire is a company that has its headquarters here in Scottsdale, [and] this collection was started by its founder, Bruce Halle, in the 1980s. He purchased his first vintage tire poster, and […] up until pretty recently, he's collected over 500 of these posters. We are very lucky to be able to have a few to show to our audiences at the museum,” shared Rachel Zebro, associate curator of collections at Phoenix Art Museum, with ABC15.
The exhibit is said to highlight developments in the automobile and tire industries at the turn of the 20th century, offering a nostalgic look back.
