They are size a2 (16.5 x 23.4 in) matte varnish on 200GSM silk paper. Each print is also signed by the artist. I previously bought his other poster print, and I was not disappointed. For the very cheap price of $10 + shipping, this is a steal. You could have it framed up cheap, and not even spend more than $50 for the whole package.
You can get both his prints so far on Bambaland
