Spain Celebrate 25 Years of Coke Light via 15k Bottles

I have written about Coke Monopoly recently and now have found another interesting article about Coca-cola. Coke is close to my heart as this is my first employer right after College.
Spain is celebrating 25 years of Diet Coke/Coke Light by building billboard made up of 15,000 limited edition Coca-cola bottles. The billboard is shown at Oscar Room Mate Hotel in Madrid.
