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.
Here’s the secret revealed. When you place a steel rod at the circle in the first pic you saw, you will see the image of the JRD Tata as a reflection on the steel rod as seen in the second pic below. Isn’t it incredible!!
