The vast personal collection of Neil Armstrong, the first person to set foot on the Moon, is to go under the hammer later this year.

Armstrong, whose proclamation that he had taken “one small step for a man, one giant leap for mankind” became one of the of the most iconic phrases of the 20th century, died in Ohio in 2012, aged 82.

The auction will include an astonishing array of artefacts from the lunar landing which took place on July 20 1969.

Lots include correspondence relating to the Apollo 11 mission, laying out the planning and even discussions with the Nasa press office as to what astronauts should say when they set foot on the moon.
