I've played poker there many a day in the 1960's. Your chip is pre that date.
We were using cash in the games by the 60's.
Lots of cheating going on in the game, mostly using "Shades"
Since I could read Shades, it was easy pickins!!

It was on Pike St accross from the Depot Cafe.
The Mag was a real dump!!!!
Not sure if its still there. Maybe Roy Kline or Jim Lunduff will see this and let us know.
