Hi all! Does anyone know anything about this shirt? I’m assuming it’s some old merchandise for this team, but I’m not entirely sure where it’s from/what time it was made.

To add some more info, I've had this shirt for about 4 or 5 years now. It basically just appeared in my household one day. Nobody in my family knows where it came from/who gave it to us. We aren't from Philadelphia, nor do any of us watch/play hockey.

It's been my all time favorite pajama shirt since I got a hold of it due to its quality and the pattern being part of the fabric instead of being printed on.

Basically all I've learned from my little bits of research is that it's from this team. I'd like to know a lot more about it, and I figured this subreddit would be a good place for finding the knowledge I'm looking for.

Thank you for reading this if you've gotten this far! Any/all information is helpful!
