Now the business he started in 1997 attracts customers for his painted eggs from Germany, France, Italy, and the Netherlands. Sadra usually experiences a surge in sales ahead of Easter.

Wim Delvoye is a notorious tattoo artist, who became famous when he started tattooing live pigs. He first began in 1997 and after animal rights activists found out about what he was doing, he had to move to China to continue his business. There is nothing special about the tattoos that Wim Delvoye creates, they look mediocre at best, and the only reason why he’s famous is his acts of animal cruelty. Nevertheless, Wim states that the pigs feel just fine and are well fed and taken care off. Full anesthesia is used to ensure that the pig doesn’t feel pain during the course of the whole procedure. During this time three tattoo artists work on the tattoo simultaneously to complete it as quickly as possible. Skins of those pigs are then sold for as much as £50k a piece.
