Is this a vintage hippie sweater made by Ball of Cotton or not?

Can anyone tell me anything about this vintage made in the USA sweater with a primitive nature loving hippie look. It looks like it was made to shock anyone who came across the woman wearing it. I can only describe it as a "Wild Nature Looking Open Knit Long Hair Shaggy Raggy Fringed Hippie Sweater or Open Cardigan". It is made of 75% Viscose and 25% Polyamide Fabrics, probably at a time when the clothing industry was experimenting with plant based sources for fabrics. Please see the picture I have uploaded. I would love to know more about this bizarre and fascinating sweater or fashion idea for such a sweater. Was it inspired by the Hippie Movement? or Other? I am a clothing reseller in training and I am currently selling it on eBay with the title

Definitely a recent sweater not vintage.
