Embroidered with iron on backside.
Bought from the bands merch table at the Helsinki gig in 2013 (Infestissumam release tour).
Was glued to a shitty fake leather jacket with some textile or contact adhesive, didnt want to iron it on, for years and some of it is still there (the brown stuff). The "T" was over a seam of the jacket, thats why the back side looks like healed scar which had stitches on it.
