first of all thank you for all who participated The correct answer to the question was 180 pieces will be exhibited.
I put all your names in a bag and my lovely collegue Emilie was the innocent hand which made the draw.
I finally managed to get 12 catalogues instead of 10 so there are an extra 2 happy winners.
To all the winners: please email me with your screen name, full name and address + phone number (DHL request)
