Sitting here in otherwise wonderful Hong Kong, we look at the sky in postcards like this and know that local children here hardly ever see this shade of blue.  As for the card, it probably qualifies as a Maximum Card because it was issued by Australia Post with “Postage Pre-Paid” pre-printed on the reverse (and postmark), but please note CAREFULLY that the stamp you see in the scan is also printed onto the card and never was a separate stamp.  Grade: 2
