Hi. Welcome.
The brown stripe makes those look like they could be Vitros. I usually expect a second brown stripe to complete the Vitro picture, and I think I see a hint of a second brown stripe on the marble the middle. But definitely on on the marble on the right. The marble on the left did initially look like an Akro to me until I saw that distinctive brown stripe.
I'm not sure what to make of the patterns here.
Okay ... I _think_ it's a figure 8. That was my first impression.
But the ribbons aren't very angled, are they. I suppose it could be a Pelt.
In this case, one might consider other clues. What other marbles were found with it?
Cairo Novelty ....
I said it with a long i, rhyming with "eye". Ki-row.
But I've heard people who knew the area better calling it something closer to Kay-ro.
