Yep, we used those in '83-86 or so when shipping individual books.
Uncommon in any condition; normally we shipped case-lots.
These would have been used primarily by the Mail Order Hobby Shop (the new incarnation of the old Dungeon Hobby Shop).

I have a dozen or two original TSR boxes, but only in 2-3 larger sizes. And mine are all beat up; been using them to store games for 30 years.
ps: Window is defined by MM2 (1983) and the move to
2e (1989), and very probably limited by UA (1985, not included on the list). So these would be fairly rare. We fixed the misspelling as soon as we printed a new batch of boxes,
iirc. (Tiny diets?) Musta been the Sloans again and their Research & Product Engineering (R.a.P.E.) Department... :/
My friends Dave & Gary made a quantum leap in entertainment. Remember them.
