Here is a vintage 1980 Queen "Live in Concert Another One Bites the Dust" t-shirt.  It is a small size.  This is in pre-owned/used condition.

The measurements are when laying flat, it is 42" across the arms.  From the back of the shirt down to the bottom is 26".  The actual collar is 7 1/2" across and it is 15" across the body area.  It is in very nice condition. There is some very light blue staining at the back of the right sleeve from being folded for many years against the word "Queen". I see a couple of teeny holes where the stitching is an the end of the sleeves.  The stitching is coming away a little bit at the end of the sleeves and there is a little loose stitching at the back of the collar. I see no other holes or tears.  Unfortunately, it is missing the tag with the side at the collar so I really do not know the size. I am not well versed with clothing at all so please ask any questions before you bid an buy so I can answer anything that you might need to know.  I have not washed this or ironed it, it is the way I found it in from a local estate.  Thank you.
