Can you draw BIG BEN without looking at it?

Can you draw BIG BEN without looking at it?

I found many tourists have cameras and keep taking many pictures at BIG BEN in London. Are they really looking at the things in detail??Or are they just taking photos of sightseeing area? I think they are too much relying on their cameras and they tend not to look at things with their eyes. I would like to realize this matter to intrigue tourists’ awareness. Then I asked them to draw BIG BEN in front of BIG BEN.
