The word "selfie" was the Oxford English Dictionary's "word of the year" in 2013. Taking a selfie is the most popular activity now, and many people may get addicted to it. However, when there was no camera, no PS software, how did people do a selfie? Maybe the only way was to draw a picture of themselves.

Some art giants were also great fans of self-portraits. Let's have a look at their portraits.

1. Pablo Picasso (1881-1973), a genuine selfie fan, who painted over 100 self-portraits during his lifetime.
