 The disaster prompted the production of collectibles and memorabilia, many of which had overtly religious overtones.Collectible postcards were in great demand in Edwardian England; in an era when domestic telephones were rare, sending a short message on a postcard was the early-20th-century equivalent of a text message or a tweet.A few postcards were published before the disaster showing "Titanic" under construction or newly completed and became objects of great demand afterwards.
