Here's a marble (posted by oldflame) which got a split decision awhile back.
I said flat out popeye. You agreed. Alan said popeye-ish and some might just call it a corkscrew because it was "somewhat lacking in the thready white strands".
You said you thought you saw some good wisps in two of the photos oldflame showed.
And my thought was "so what if you couldn't find any wisps?" What if it was solid white inside the clear, without any stray white strands? I was fascinated by the idea that the marble was part of an Akro tri-onyx run and would have been sold in a Popeye box, but that was somehow not enough to make it a Popeye.
