Wanted: Deadstock real vintage t-shirts

Hello, I know this is an unusual request but I was wondering if any of you have old blank t-shirt stock from the 1980s or 90s? I’m working on a project which calls for deadstock T-shirts and Long-sleeve T-shirts from the 1980s (Hanes, Fruit of The Loom, Screen Stars, Miller, Oneita, etc.) Could you let me know what you might have (sizes, brands)? If you don’t have anything, do you know who might have what I’m looking for? I’m eager to buy.

Thanks in advance!
