(my other link was defective) It's done on dumpster wood with a calligraphy pen and an ink well. But! It's The Plummer, I think all I have left to do is paint the background some solid colour (kind of like others in my gallery) It's actually quite large, I'd compare it to a large couch cushion lol.
