The contest rules said "In presenting to our juvenile customers this beautiful new line of marbles, we have been at a loss to find a suitable name to describe them, therefore we will put it up to our boy and girl friends to give this new marble a name."
But in the end they ignored that part. Awarded the money but didn't use the winning name, or not for these marbles. Kept calling the marbles Prize Name. Funny choice!
Akro does have a Fire Opal of course. Were they thinking of young Paul Chadbourne when they named those?
