Vintage Unique Firestone Advertising Newport Tennis Racket - Very Unusual

Description

Vintage Unique Firestone Advertising Newport Tennis Racket - Very Unusual. Condition is Used. Shipped with USPS First Class Package.
Very unusual crossover advertising piece. It’s definitely a unique piece, but awfully curious why firestone would put their logo on a tennis racket? I’m not familiar with any connection...
As seen in the photos, the rackets integrity is still in tact, but the paint is chipping away. Luckily enough, the firestone logos still display pretty nicely.
Thanks for looking!
