Samoa was a German protectorate between 1900 and 1914.
Called 'To Walk Under Palm Trees', the book contains rare photos, many sourced from family collections.
The books author, Tony Brunt, said the pictures had captured historical moments in Samoa.
"One of the primary motivations is to get these photos that are historically significant out of purely private collections and into the digital archives of the Museum of Samoa," said Mr Brunt.
