Vintage T-Shirt Forum & Community Authentication Appraisals

Hi I have this shirt, the label is white, it's single stitch. The size by the measurements gives XL(24/27). I can't find it anywhere. So I'm asking you. I'll say 80 dollars, but I don't really know.
I have a 1989 batman and now it's worse. I did see the top of batman sold on the site but looking on eBay, I would say a value of 40 dollars. I can't say what makes batman high-value. Thanks

Batman likely in the $100 range - is the Spiderman a kid's tee?

Hi thanks, The Spiderman is XL Men's (23 inch. Pit, 27 length)
Thanks

Ah yes, sorry I missed that.

I'd put it in the same price range, the Spider-man tees that $$ are usually comic images related or an AOP.
