This pic is taken on the ground floor where the exhibition of the museum is displayed.....and where wardens are guarding every corner ...i did know that it wasn't allowed to take pictures in the exhibition, but i didn't think the no-pics rule would extend to the staircase...the warden was already looking at me when i raised my camera, so i lowered it again and held it hidden near my hip.... this is the result

wonderful picture! that's really great!
thank you for outsmart the wardens!

Geniale Wendeltreppen wieder!!!

Magnifique !
