Pamplona is commonly known for the running of the bulls. In fact, I will be there in March so it's totally not the San Fermin day, but I'm sure it must be even more exciting place then. I really like a series of posters dedicated to this day. It's a fine example of art evolution – we can find some art nouveau, some cubism there.
I like the most the poster from 2013. It's expressive and different from the majority because it refers to the urban structure of the city not exactly to the dynamic run. Maybe it's my weakness to the urban planning but for me this poster creates completly new ambiance and way of thinking about the San Fermin event, as connecting the whole city and being a part of an urban activity.
