Some stamps relevant to today. Four stamps featuring Neil Armstrong, Michael Collins, Eileen Collins and Cady Coleman. Issued appropriately on 4th July. The Stamps officially commemorate Space Exploration but two of the stamps reference the Moon Landing (Armstrong and M Collins) The other two are astronauts of Irish heritage. It is an odd issue which does not really satisfy the theme. General Space Exploration would have featured a cosmonaut. Moon Landing would have featured Aldrin. And Irish heritage had some other possibilities eg the Kelly twins. And it seems a pity that Chris Hadfield of Canada was not included.
