Grecia alla vigilia del referendum

A "NO" referendum campaign poster is seen before a statue of Greek Godess Athena and a Greek flag outside the Athens Academy, Greece, July 4, 2015. With less than 24 hours to go until a referendum on the conditions of a new bailout deal, Greek officials prepare polling stations, as the latest opinion polls show ‘Yes’ and ‘No’ sides neck-and-neck.
