 It can also be found in Beagle's short story collection "The Line Between" (Tachyon Publ., 2006); in the deluxe edition of "The Last Unicorn" (New American Library ROC, 2007); and in "The Very Best of Fantasy & Science Fiction: Sixtieth Anniversary Anthology" (Tachyon, 2009).

 It was produced by Rankin/Bass Productions for ITC Entertainment and animated by Topcraft.
 Based on the novel "The Last Unicorn" written by Peter S. Beagle, who also wrote the film's screenplay, the film is about a unicorn who, upon learning that she is the last of her species in the world, goes on a quest to find out what has happened to the others of her kind.
The Last Unicorn is a fantasy novel by American author Peter S. Beagle and published in 1968, by Viking Press in the U.S. and The Bodley Head in the U.K.
 It follows the tale of a unicorn, who believes she is the last of her kind in the world and undertakes a quest to discover what has happened to the others.
 It has sold more than five million copies worldwide since its original publication, and has been translated into at least twenty languages (prior to the 2007 edition).
 In 1987, "Locus" ranked "The Last Unicorn" number five among the 33 "All-Time Best Fantasy Novels", based on a poll of subscribers.
 The 1998 rendition of the poll considered many book series as single entries and thus ranked "The Last Unicorn" number 18.
The Hunt of the Unicorn, or the Unicorn Tapestries, is a series of seven tapestries dating from between 1495 and 1505, now in The Cloisters in New York, probably woven in Brussels or Liège.
 The tapestries show a group of noblemen and hunters in pursuit of a unicorn.
 The "Hunt for the Unicorn" was a common theme in late medieval and renaissance works of art and literature.
 The tapestries were woven in wool, metallic threads, and silk.
 The vibrant colours, still evident today, were produced from dye plants: weld (yellow), madder (red), and woad (blue).
 One of the panels, "The Mystic Capture of the Unicorn", only survives in two fragments.
Rankin/Bass Productions, Inc. (founded as Videocraft International, Ltd.) was an American production company, known for its seasonal television specials, particularly its work in stop motion animation.
 The pre-1974 library is owned by Universal Studios (via DreamWorks Animation/DreamWorks Classics), while the post-1973 library is owned by Warner Bros. Rankin/Bass stop-motion features are recognisable by their visual style of doll-like characters with spheroid body parts, and ubiquitous powdery snow using an animation technique called "Animagic".
 Often, traditional cel animation scenes of falling snow would be projected over the action to create the effect of a snowfall.
