When I say the writing is in English, I am referring to things like "World Cup" as being in English. "World Cup," the Olympic rings, and maybe some of the other things are copyrighted and registered. They have to be used as is. You won't see official material written any other way that the registered trademark. So anything produced anywhere in the world that says "World Cup" will have it written that way and not in any other language.
I don't think we have tunnel vision when it comes to saying what they are. The items shown as "Jack Stones" are exactly the same shape. Octagonal and capped on each end. They are exactly the same. Can't be coincidence.
