Celebration of forty years

Most people have a similar photo in their portfolio, but this weekend being the fortieth anniversary of the Sydney Opera House I thought it appropriate to upload this one featuring not only the Opera House but also the Harbour Bridge.
Last year celebrated the eightieth anniversary of the opening of the bridge so these two icons together make a great sight.
I can remember as a boy, the old tram shed on the site of the Opera House then known as Bennelong Point.
Queen Elizabeth opened the Opera House in October 1973.
