For the moment I used the illustration of Kiraz "les parisiennes" to illustrate the blog, I did not want to use the eiffel tower used by others.

I could use now a symbol of Madrid but the problem is there is no very clear and nice symbol of Madrid...
So I think the best is to play with the name "une Parisienne à Madrid" around the idea of tourism, restaurants, discovery.
Thank you!
