I was cleaning out my grandparents barn this afternoon and came across a bunch of cigar boxes, wooden and cardboard. Some were not in good shape but one in particular caught my eye.
It is wooden and stamped with The Plaza hotels logo and reads "Specials Manufactured Exclusively for The Plaza New York" this is also on the inside when you open the box. On the side it says Boite Nature. It is stamped on the bottom, which factory it was from and a notice. On the front where the clasp is, (which is metal and slides back forth) is another stamp of how much the cigars should sold for.
All I have been able to find out so far is that the box is made similarly to other boxes that have Boite Nature on them and that from the stamp it probably is no older than 1960.
I would love any information anyone could offer. When The Plaza may have had their own cigar boxes? Value?
