For the theme of archaeology, Egypt has plenty of stamps to choose from, so I think I found a set I haven't posted before. Issued in March 1947 for the 25th International Exhibition of Contemporary Art, the designs all have archaeological connections.
The 5ml depicts the 'triad of Mycerinus' whose tomb is the third of the Giza pyramids (wiki link).
The 15ml shows the mortuary Temple of Ramses II (the Ramesseum) on the West Bank at Luxor (wiki link), the stamp is not quite so blue in reality.
Then two very well known faces of the past - Nefertiti on the 30ml (wiki link) and the mask of King Tutankhamun (wiki link).
I'm participating in Viridian's Sunday Stamps, clicking the icon below will take you there.
Thanks for visiting.
