The Australian stamp issued to honor the
World Centennial of the Y.M.C.A. in 1955 features a world map on an
interrupted projection (a modified sinusoidal, according to Walter
Klinefelter, CP 2:4:11). The northern hemisphere is completely in
daylight, while the soulthern hemisphere is in the dark. For that to
happen the sun would have to be directly above the north pole, which
of course is impossible.
