Vintage Philadelphia Phillies Snap-back Trucker Hat

I couldn’t place the year for sure. Sometime between 70s-80s I think. Awesome vintage piece for a collector. Flaws to note: some yellowing on thread & inside lining, and most snaps on the back closure are broken. Still functional, but only to one snap fitting. I tried to capture photos of any flaws.
