As in any hotel, virtually every object used by passengers carried the ship’s, or at the very least the line’s name and logo. There is a practical if somewhat morbid rationale for labeling a life preserver  with a ship’s name, but in other cases the sole impulse was promotional. As a marketing device this made good sense. Officers habitually gave certain items, like cups and saucers , to special guests as mementos of their passage.
Decks of cards  and the like were sold aboard ship. Some items were available for free but were intended to be used only aboard ship, such as scoring pads for bridge . Accoutrements for general use—like stationary portfolios , room keys , and ashtrays —were supposed to stay with the ship from voyage to voyage.
A significant number of passengers pocketed keepsakes after each voyage, and the replacement costs could be exorbitant. According to a Cunard spokesman, when the Britannic “made her maiden voyage to New York [in 1930], we lost $55,000 worth of silverware alone”—about $750,000 in today’s currency.
