A sailor's valentine is a form of shellcraft, a type of mostly antique souvenir, or sentimental gift made using large numbers of small seashells.
Sailor's valentines are typically octagonal, glass-fronted, hinged wooden boxes ranging from 8 to 20 inches (20 to 51 cm) in width, displaying intricate symmetrical designs composed entirely of small sea shells of various colors glued onto a backing.
Patterns often feature a centerpiece such as a compass rose or a heart design, hence the name, and in some cases the small shells are used to spell out a motto or sentimental message,[1] such as "Forget Me Not" or "Home Again.
[4] The art form represents a fusion of European and West African scientific and spiritual, aesthetic, and cultural practices of shell collection and display.
[7] Fondas recounts that while an antique sailor's valentine was being repaired and reconstructed, pieces of a Barbados newspaper were found inside the backing material.
