Any idea or informations on who or where can I probably sell this piece?

This is very cool, I've never seen this HT tag before, not that I can remember anyway. I've attached the one I have seen before but yours appears to be a bit of a relic. Can't find it using google lens.

Anywho, absolutely authentic.
