They may look like pin-sharp photographs - but these amazing pictures are actually drawings created with the humble ballpoint pen.
The stunning pictures, measuring up to 10ft high, were drawn by a rising star of the art world, Juan Francisco Casas. Casas, 31, can use up to four 14p ballpoint pens for a canvas and his works are already a sell-out at exhibitions. Formerly a traditional painter, Juan began the drawings three years ago based on photographs of nights out with his friends.
"For me it's not that different from painting. I was trying to show that it doesn't matter what material you use, it's what you do with it." - Juan Francisco Casas
