Oyster Card - название проездного на все виды транспорта в Лондоне. Кто знает, откуда взялось такое странное название?
Мне уже успели помочь, но тем, кому интересно:
The Oyster brand name was agreed after a lengthy period of research managed by TranSys, the company contracted to deliver the ticketing system in London, and agreed by Transport for London. Several names were considered, and Oyster was chosen as a fresh approach that was not directly linked to either transport, ticketing or London. According to Andrew McCrum, now of Appella brand name consultants, who was brought in to find a name by Saatchi and Saatchi Design (in turn contracted by TranSys), Oyster was conceived and subsequently promoted because of the metaphorical implications of security and value in the component meanings of the hard bivalve shell and the concealed pearl; the association of London and the River Thames with oysters and the well-known travel-related idiom "the world is your oyster".
