All of Juan Francisco Casas’ pieces are drawn exclusively with Bic biros. Hundred and hundreds of Bic biros. Thousands of them. Squillions. He’s probably responsible for certain species of squid becoming endangered with all of the ink that he saps. Not that we mind though, because the pieces that come out of it are somwhat amazing. Often a couple of metres tall, the detail and precision that is required to create such work makes our eyes go fuzzy. Someone give that man a stationary sponsorship.
