Thanks for the Paden City info. That's what I sorta remembered but it's so hard to mesh the marble structure with other Paden City marbles, isn't it.
In the 30's he was trying to find ways to sell more Pelts, so I figured he gave away Rainbos. He told a story of holding out handfuls of marbles to see what the kids chose, and red was by far the most popular. That could explain why Pelt had assorted boxes and boxes just of bloodies.
But someone once -- was it Lloyd -- showed a picture of a Berry Pink agate. If I'm remembering right. And I've wondered if he was giving those away to kids before his Marble King days. Or if those were souvenirs for adults. Has anyone ever seen more than one of those?
