This instant stamp sheetlet issued by Australia Post celebrates the birth of a Prince to the Duke and Duchess of Cambridge on 22 July at 4.24pm BST. The newest member of the Royal Family was introduced to the world the next day on the steps of the hospital, with his proud parents. The Duke and Duchess of Cambridge have since named their son George Alexander Louis.
The stamp features an image of the Royal couple leaving St Mary's Hospital Paddington with their newly-born son.
The birth of a future monarch is always a highly anticipated event and the child of the Duke and Duchess of Cambridge, who will be third in line to the throne after Prince Charles and Prince William, was no exception.
For the first time in British history the gender of the newborn royal was irrelevant - the newly altered Act of Succession means that now the first born, whether boy or girl, will be monarch. And in another first, the birth of this royal baby saw Prince William take paternity leave from his position as a helicopter rescue pilot.
The sons of Her Majesty Queen Elizabeth II - Charles, Andrew and Edward - were born at Buckingham Palace, while Princess Anne was born at Clarence House. Today the preferred birthing facility used by the Royal Family is the Lindo Wing at St Mary's Hospital in Paddington. The baby's father Prince William was born there, as was his uncle Prince Harry.
A notice of the birth was attached to an ornate easel in the forecourt of Buckingham Palace, with the media officially informed. There were royal gun salutes across London heralding the new arrival.
The designer of the stamp is Sonia Young of the Australia Post Design Studio.
