I love this tag! This shirt is from between 1976-79 when Furay was signed to Asylum. This is the first vintage t-shirt I ever picked up, though unfortunately it's a small so I could never wear it...something that has pissed me off ever since..
I still don't know much about this company. Though someone has an Etsy listing claiming a gaudy Hawaiian shirt with the HWNICBW tag is from the '60's....
