A man passes by an installation by German artist Max Neupert in a subway in the city of Plovdiv, some 120km (75 miles) east of the capital Sofia December 18, 2006. The installation shows the flags of the former Soviet Union and the European Union and represents the author's view of the reorientation from East to West, a result of the accession of east European countries to the EU. Bulgaria is set to join the European Union on January 1, 2007 along with its neighbour Romania. REUTERS/Stoyan Nenov (BULGARIA)
