At first sight they may look like some pretty sharp blue photographs, however all those pictures are actually hand drawn with a simple Bic ballpoint pen!

Spanish artist Juan Francisco Casas uses up to four 14p ballpoint pens to create his incredibly photorealistic drawings, measuring up to 10ft (3 meters) high.

The use of penballs makes Juan’s drawings even more original, which certainly has played a big role in his way to success, and his works are already a sell-out at exhibitions.

His source of inspiration comes from his own photographs of nights out with his friends, so you can only imagine how wild his parties are, as half of his drawings include girls that forgot to put on their clothes.
