The "P" on Tom Ewell's hat (and his assistant coach played by Dean Jone) is supposed to represent their team mascot "the Panthers." However, it's the script style "P" of the 1950s Philadelphia Phillies that Ewell and Jones wear. The Phils were known as the "Whiz Kids in the Fifties and had many fans around the country. Curiously, the kids on the team wear hats with a different "P" style on their hats. Maybe Ewell or Jones were Phils fans.
