Penn Celebrates 100 Years of Excellence. Starting in a small town in Jeanette, Pennsylvania in 1910, Penn is still going strong in 2010 and continues to be America's Number 1 Selling Ball. As a tribute to our 100 years of excellence, we wanted to share some of our vintage tennis ball ads, so you can see how far we've come.
