Box is legit. I have seen similar crew stamps on other vintage boxes. Alot of the union shops were proud of the boxes they produced and proudly marked them. It was also a great way to trace back if there was a quality issue.
Someone got themselves a casting kit for Xmas obviously. :lol: Non-Articulated and rough casts. Also If you look close on some of these..he went really thin on the paint.
I see them more as a souvenir and memory for me going. These jokers think they are gold and want to flip them. Almost as bad as the celebration store pins. Anyways.. May follow what Ben has suggested.
