Vintage T-Shirt Forum & Community Authentication Appraisals

Just found my old Castle Donington t shirt and it's different from everyone else's that year.
Now it's been many years and I cannot remember how I got this one one the day.
Anyone help me out with this?

Very cool oddball one. Must be some explaination for it - maybe ZZ had frilly shirts like that in a video? it looks like my wife's traditional Ukrainian shirts.

Value wise...i have found these oddball tees to not be super in demand. i could be wrong but i think people want standard tees. perhaps its so rare and theres some ravenous donnington fans out there?
