dating of a hat - bollman & co

[fanciness]

I need some help with the dating of this hat and info about the maker. I couldn't find much information about this label, but a wpl search yielded this:

so apparently it's part of the bollman company? The paper size tag has me confused about how to date this one (I'm not too familiar with dating hats just yet!) Thanks in advance!

It looks like a 70s hat to me. This style was quite popular at the time.

It could even be later as the Bollman Hat Co is still making hats today.
I suspect more modern.
