Disigner, Draftsman, ... I need you Everyday life and customs

Hi everybody and Welcome !

As you're already read it, I need some artistic minds cause mine, I'm afraid of it, is as developed as a worm :/

I opened this topic to find help to customize a road sign that I found during a party (see https://image.noelshack.com/fichiers/2017/35/5/1504261387-panneau.png ).

What I would like to have is "a door opening on a new world", a little like the Hobbit Door (See https://image.noelshack.com/fichiers/2017/35/5/1504260985-hobbit-dorr.jpeg ). The "New world would be draw on the white part (Diameter 50cm / 19.66 inches ) and it should be draw with a black marker (a black and white drawing) ;) .
You could, obviously, mix it with your inspiration (That's why I'm here to propose you this ;) cause I think it could be cool to see the influences of your country :D ).

So let's your imagination.exe run and hope you will draw some great things :) ,

Kan je dat vertalen naar het Nederlands? C'est quoi en français?
