This mug satchel or "demitasse" in French was used in first class on several White Star Line ships including Titanic.
The mug satchel is decorated with a colour combination of turquoise and brown and a gold rim, the most famous motif used for White Star Line porcelain. It is also featured in James Cameron's 1997 film Titanic. The motif has no official name but is commonly known among collectors as "Wisteria" (or wisteria) because of its resemblance to the blue flower clusters of this garland plant.
