In the previous agralekh, bapu has mentioned about the Dragon submarine which was 2300 feet long in length with 2 dragon heads.
Just came across a similar image on web. This image is taken from a comic book, but it resembles the structure of the dragon submarine.
It is mentioned that it is a gigantic submarine in the shape of a Dragon, whose hull could contain many ‘Battleships’.
We can see various floors and people moving around in this particular picture.
