Daniel Reeve is an artist and calligrapher who created the maps and calligraphy for the Lord of the Rings and Hobbit films, including the contract from The Hobbit: An Unexpected Journey.
I had read Tolkien’s books as a teenager, and had tinkered with calligraphy – including elvish calligraphy and runes – ever since then, so when I heard that The Lord of the Rings was being made into a film, practically on my doorstep, the opportunity was too good to miss. I submitted some samples of elvish calligraphy to the film company; they phoned me immediately, and the next thing I knew, I had the job of doing all the calligraphy for the films.
I thought that the contract was particularly well done, and a that the implications behind it - that the Dwarves as a race were very much legalistic, fastidious about details, and concerned with recording even the most minute detail of an agreement - helped more than anything else to set the character of the Dwarves' background. Compared to that contract, you can see just how flighty most of the Dwarves really are; which in turn makes it obvious how seriously Balin and Thorin are taking the enterprise.
