the BESt authentic vintage tee from the Melbourne Blues Festival in 88.
Label has gone but feels soft and worn in like a poly cotton blend.
Its a dark grey marl look fabric with white print on the front.
Single stitch.
Has wear hole up near the collar, runs/holes in the fabric on one side at the front and hole under the other arm.
So nicely worn in and thrashed!
I think its about a size medium, please check measurements.
