Remember the colouring books you used to love in your primary school days? They used to be the best gifts for some. I am sure, everybody also share the memories of drawing or sketching funny things in the back or in the margin of their notebooks, during some boring lecture. It used to be the only and a good option to survive the boredom. But it became a hobby and later a profession for this Japanese artist Keita Sagaki. But he brought a twist.

He merged his love for drawing cartoons and interest in famous art works. And he did that very finely. His art works may look like simple drawings from a distance, that too uncolored. But when you have a closer look at them, you find doodles all over. You will end up searching for your favorite characters within them and also refresh some childhood memories.

We all doodle once in a while but I bet no one doodles like this anonymous Spanish artist, who is known all over the web-space as 'The Postit days'.

This artist uses a rather unusual canvas for his artwork and that is the boring Post-it Notes we use in our office and at home to remember important things and get work done.

The artist perfectly doodles pop culture icons, comic and cartoon characters, imaginary situations on to Post-it Notes.

You can find the artist's work on Facebook and Instagram.
