In this tribute to US President Barack Obama, notice the intricate detailing and clean strokes

From far, it might look like a regular drawing of a hot-air balloon, but draw close and the details begin to emerge - a tiny suitcase and a passport here, a camera and the Eiffel Tower there. Tanvi Mehta of Ink Tales has created these intricate drawings using nothing more than pen, paper and her imagination. Now, you can also learn the art from her at a workshop this weekend.
