A2 (420 x 594 mm) digital inkjet printout on photo paper. Doesn't fade, decent stuff. I will sign it unless you tell me not to. Other sizes available too, let me know if you want something else, up to 1000 x 1414 mm is possible, in case you're crazy like that. I'll need to check out the prices for printing and shipping then.
This is part of my Buffalo Bill Gates project. Which apparently is what I was put on earth to make. Mashups of celebrity names and faces, which make your synapses vomit.
