Airplane seat row indication signs - good and bad designs

Aeroplane (bus or whatever vehicle) seat row signs can sometimes be problematic. This happens when a sign doesn't picture the passenger in relation to the seat and the window. For example this one that assumes everyone speaks English:


This one for example shows just the person. I'd assume that the person stands in the aisle and the nearest seat is E or D


This one shows the window only but I like its 3D perspective - very intuitive.


Here is one that shows both window and the person in the aisle. But NOT the seat letter??!?

As it should like on the below example:

However my favourite is this one - very intuitive again!
