Igrew up in South Philly Graysferry sectionand we use toplay what you call Skullys. We use to call it street checkers the same as Al politowlski called them.That was back in 1940 and I don’t remember all those rules. We use to use the liquor bottle tops and cut the neck off when we could find them . No body would let you use theirs and you didn’t loose them.The looser of the game first man out had to put the winners name on a shirt with bottle caps and the cork inside the cap. We moved to West Philly they called it the same, street checkers but some rules were different. I’ve been telling my wife about this game, now ican finally show it to her thanks to you. Ihave acouple of liquor tops and i would love to shoot agame.IfIloose I’ll put your name on a shirt for you.
