Thanks for sharing. Richard Maxwell, who does a lot with kids and marbles in the Kansas City area, visited Wildwood this year for the tournament and posted a lot of pictures in some of the Facebook marble groups (or on his own FB page).
The three middle ones might show up in a Chinese Checkers type box that has Champion marbles in it as many game marbles have a pattern to them but I would say these are not game marbles but Champion marbles.
I think they are relatively new - meaning the last 5 years or so - but no definite reasoning other than I bought mine in the last year and I am always buying any bag style that I don't have so I must not have seen them much prior...?
