@Al Oregon may know these.
I have not seen this bag before as far as I can recall.
I am glad to see that the name is advertised as far as the maker/seller of this bag goes.
It carries the attributes of a vintage bag of marbles, including the seam on the bag itself. The staples are just wrong.
This one saw too much sunlight and the header—the tag that is attached to the bag, is wilted and washed out.
It is just a knockoff that carries--- imho—newer Marble King marbles.
I am sorry to say that there is little value here.
It is a cool find for sure!
Marble—On!!
