Regarding the funny and special email footer, Corinne Weber came back to me with an official explanation from the NH Hoteles Head Office in Spain. I quote:
"The drawing is just an adaptation to electronic communications of our new corporate image. The entire new NH Hoteles graphic image is based on this kind of graphical solutions and a new corporate color.
In the email signature application it represents somehow a signature…a drawing hand made, human. It is electronic communication but still personal."
Great, isn't it? In the time of stereotype communication they go their own unique way. If they have properties like this then this soon will be one of my favorite hotel chain.
