Here is the map and you can also have download my pdf which includes what I have found so far… An update will come when/if I go to Bern!
PS: I went to Bern on June 15, 2014. A strange coincidence étrange is that I finished reading that day La Vie mode d’emploi by Georges Pérec. I thought then that Bartlebooth is a kind of analogy for Street Art and its fans… I just updated also the pdf above and here are the ones which survived after nearly 15 years. Another coincidence: they are 8 surviving pieces out of 29, similarly to start-ups where 50% still survive after 5 years and about 25% after 15 years…
PS2: from time to time, I add chapters to my Space Invaders discoveries. Here is a synthesis essentially based on the artist site and using other passionate data: SpaceInvaders around the World (pdf – 8Mo)
You may find in other posts data about Lausanne, Geneva, Basel, Grenoble, Brussels. In September 2014, I began to compile data about Paris. Here are pdfs files about specific arrondissements:
and also the 1000+ Paris Invaders. Below is my Paris map.
You will find more recent Paris data here.
In October 2014, I followed in invasion of Ravenna. Here is what I found on line: Space Invaders in Ravenna.
