Vintage T-Shirt Forum & Community Authentication Appraisals

Came across this jacket and I know it is an oldie, but a goody. I believe it to be authentic. Can anyone give me any information on this ZZ Top 1983 Eliminator Roadie Tour Jacket and let me know what they think?

It is on auction now at:

For sure it's authentic. I've sold quite a few tour jackets in my day, never a "Roadie" brand though. I've never had much success with ZZ Top related stuff - even a rare t-shirt from 1975 New York Felt Forum didn't fetch a lot.
