This simple black and white line drawing of a polar bear is available to download as a scalable vector graphic and as a transparent png.
The artist that created this said it's a picture of Knut, the polar bear that lived in the Berlin Zoological Garden for over 30 years, probably one of the most famous bears of all time.
A very cute polar bear, leaning back holding onto it's back paws with a big smile on his face. It looks like he (or she) is ready to play.
Normally I don't put photos on here but this on of two lounging in the snow is far too cute to skip!
