The Champion brand is not the well known American brand but a China made one. Very old style gold thread tag, possibly from the 60's. Excellent condition, one small stain on the sleeve end which I did not try to wash out.
Tag was loose on one end, but I have carefully handsewn it on discretely at the same place it was originally sewn.
Size on tag is 6X. Which may be smaller than modern 6x. see pics for measurements.
