Has anyone seen a review or study of hang tags?

[Paladin]

I have a couple vintage Rolex watches and while I will never get the original papers, I want to assemble the rest of the " complete package" I see referred to on this site often. There are some posts in the reference section on boxes but nothing on the hang tags.

My Rolex watches are from 1971, 1977 and 1984 according the the serial numbers and the information in the reference forum.

Thanks to anyone who can shed some light
