Samuel Silva, a 29-year-old Portugal-based attorney, describes his artwork merely as a hobby, and Bic ballpoint pens – as only one of the mediums in his creative work. It takes time to believe that his drawings are not actually photographs, and then to absorb the information that they were created using only 8 different-colored pens.

At a glimpse they may look like some pretty sharp photos, but actually all those pictures are hand drawn with a humble Bic ballpoint pen! Can you believe that?

Human eye can be fooled so easily!

Spanish artist Juan Francisco Casas, who’s probably 33 at the time of writing this, uses up to four 14p ballpoint pens to create his stunningly photorealistic drawings, measuring up to 10ft (3 meters) high.
