The Design Museum has added 13 objects to its collection of iconic designs. They include a The Face magazine, the Space Invaders arcade machine,  Sony Walkman, and Margaret Calvert and Jock Kinnear's motorway signage system. Controversially, the addition also includes the Kalashnikov AK-47 rifle, which is undoubtable iconic, but also resposible for tens of thousands of deaths worldwide every year.

The museum notes that its acquisiution of the Sony Walkman "marks its journey into obsolescence". Nevertheless, they note, the term ‘walkman’ is preserved in the language, listed in the Oxford English Dictionary as a description for any cassette player.

In a release, the Design Museum says that it is "developing its Collection ahead of its relocation to new premises at the former Commonwealth Institute, Kensington in 2014. This new Design Museum with interiors designed by John Pawson will be three times the size of its current home and will create a showcase for its world-class collection, and greatly expand its education and public events programme. The new Design Museum will be a platform for promoting design as a national asset, and supporting the next generation of creative talent."
