A steamer trunk is a type of luggage that was popularized in the late 19th century and used primarily for long journeys on steamships or trains. This type of trunk is often made of wood, metal, or leather and has a rectangular shape with rounded corners. Some synonyms for a steamer trunk include a travel trunk, a vintage trunk, a chest, or even a treasure chest. These trunks were often used to store and transport belongings, such as clothing, books, or heirlooms, and are often sought after as unique and decorative pieces for home decor.
