French Southern and Antarctic Territories 1957 –
International Geophysical Year

This trio of stamps, identical apart from their colours, was released in October 1957 to mark the International Geophysical Year. Each illustration shows radio aerials for studying the Earth’s ionosphere, a scientist with a theodolite and, above it all, some impressive auroral folds and bands.
