Vintage T-Shirt Forum & Community Authentication Appraisals

Hi, you guys know what this shirt is worth?
It has some small stains but is still in great condition (no holes, still pretty white)
Size: XL (27,2 x23,5 Inches, Single Stitch on Bottom Hem and Sleeves)
And is it a euro tee as it doesnt have the brockum tag this shirt usually has?

Lots of legit reasons why it wouldn't have a Brockum tag, so no worries there.

These seem to max out in the $350 range.

Some going for as low as $150 in 2024. Which is odd, great shirt.

Does the tag have anything on the back, want to learn more about that one!

Thanks a lot.
Yeah that´s the back:

Doh, no RN, oh well thanks!!
