art... expect that from a street artist

Here are two pics of an amazing piece of art.
Location: Tata Museum ,Jamshedpur .
In the first pic, you can see a painting. This was a gift to JRD Tata on his Birthday by a street artist. Nobody was able to understand his art. Unfortunately, only the painting was given to JRD and the artist had promised to reveal the secret shortly . However, JRD was no more when the secret was actually revealed .
