Yea, the cats eye I threw in there, just as a size comparison to the black and yellow one.
I've got a dozen or so marbles from metal detecting, random finds cutting a plug...always cool to find one unexpectedly...
Do you want better pics?
If you'd like to know who made it, closer pics in clear focus would help (but I can't guarantee I can ID it ). It's cool to know the history of them and who made them, but other than that, this marble won't have much of any monetary value because of condition.
