I won a lot on Ebay, mixed vintage. My 10 year old grandson has really gotten into marbles. When they showed up, before opening the box, I told him we would draw straws to see who picks first then take turns picking one marble until they were split even. He drew the long straw so he went first. It got really interesting when we opened the box.
He had been studying while I was away at work. He made my ass twitch with his first few picks. I was surprised how much he had learned. Haven't laughed that much in a long time.
Just thought I'd share the story
