Thanks Steph,
I think that these originals with the brown included were more of a limited production marble.
The boxes were made and purchased--stockpiled and the more colorful “Uniques’” were sold as such.
The boxes that were recently being sold on e-bay are very “unique” to each other for sure and they are all Akro.
I really doubt that the sale to Master had anything to do with the naming of these.
Of course—this is all speculation and I just love this stuff----
Marble—On!!
