This is one of the next swap I participated in... This is the info I wrote on the back of my Postcard;
"Our Sydney Opera House is one of the most recongisable images of the modern world, it has become to represent 'Australia'. Designed by Danish architect Jorn Utzon, & was opened by Queen Elizabeth II, Oct 1973. The Opera House is situated on Bennelong point, the view of the skyline of the Harbour Bridge, the blue water of the harbour and the Sydney Opera House, is dramatic and unforgetable."
