[3] During the Second World War, Smith worked as a draughtsman, for instance producing technical drawings for the development of the Bailey Bridge in Christchurch, Dorset.[3][4][5].

[4] "Smith’s objects became bigger, more elaborate and less toy-like, based on childhood memories and colourful characters, witty but a stringent comments on society.

"[4] The Victoria and Albert Museum says that "His work has been described as "sculpture toys for grown-ups" ... by the 1970s they had become quite large, with unusual themes".

[4][7] Smith continued to be successful in the United States of America with less of a reputation in the UK until Bristol Museum & Art Gallery held a large-scale exhibition in 1972.

Later, he signed items "Sam Smith, Genuine England" as he became successful and sold work in London (for instance at the Primavera Gallery)[3] and New York.
