They're handmade gold marbles with white stripes. Here are some examples.

Yah, I remembered the "Blue Devil" discussion.
I'm not sure what the color is exactly on Howard's marble there. I was viewing it as white or off white when I first posted. And that ebay link looked white and said off white so that was good. I didn't know the range of colors available on the blue base.
Clearing up one technicality -- Akro made corks during 1930. And possibly during 1929.
The Prize Name contest which came with the introduction of corks ended in May 1930.
I watched that one episode. We don't have cable so I don't know if I'll get to see any others.
Sometimes I like lolspeak. Sometimes it's so bad, I won't post the picture. Most times I don't notice whether it's there or not. The lolcat Bible wouldn't be the same without lolspeak. (We'll discuss the future of my blasphemous soul at a later date.)
I love "o hai!" for cute aminal hellos. ( :
There's a marble I thought was a Master but the more I look at it, the more I think maybe Vitro. Sorry, no pix on this end.
But if you have any you could share of blue based Vitros, it would be much appreciated. Thanks!
