Titanic merchandising encompassed a wide range of card forms. One of the most visually attractive of these was the ‘prismatic’ or ‘prism card’. Prismatic cards gave the film’s varied images enhanced charm by incorporating an underscore of geometric patterns and colours. Often, the same image card was minted with many different pattern underscores. These cards were also double-sided. On the front was the prismatic image and on the back was a different matte image. Interwoven with the Titanic images were non-Titanic images of Leonardo DiCaprio. It is generally unknown just how many prismatic cards were produced. The prismatic cards in our collection are all mint in condition and represent the widest range of any still known to be in existence.
