Whilst hardly anyone in this galaxy or even others far, far away can have avoiding hearing about Star Wars, all but the shows most ardent fans could be forgiven for being unaware of the Christmas or Holiday Special, created in 1978.
The plot starts from the idea that it is Life Day (a holiday analogous to Christmas). Chewbacca is on his way home to see his family and to celebrate the holiday, accompanied by his friend, Han Solo.
Not long after departing Tatooine in the Millennium Falcon, the duo find themselves chased by two Star Destroyers. The rest of the show includes the wookie family dealing with a stormtrooper invasion of their home until the familiar characters return to save the day and settle down to a feast.
Although some enjoy a cartoon introduction of Boba Fett, the show is not popular with the Star Wars cast and crew, especially George Lucas, who has made comments about what would happen to all the copies of the show if he owned a mallet and a time machine.
Nevertheless, it is often collectibles from the more obscure and less popular aspects of famous shows and actors which prove to be investment-grade. In fact some of our favourite Star Wars collectibles are not what you would immediately think of.
Freeman's Vader Project auction saw the sale of a number of versions of Darth Vader's world-famous helmet adapted by contemporary artists going under the hammer.
Huck Hee's "Kurai No kurai" Darth Vader design, which depicted the iconic helmet as a samurai warrior was a great surprise: The art piece had been expected to sell at an estimated price of £2,000-3,300 ($3,000-5,000) but sold for an impressive £7,100 ($10,880) on the auction block.
Whilst Mister Cartoon's hypnotic "Darth Fader" brought £11,600 ($17,500).
Just last month, Heritage sold a Star Wars Ewok Costume Mask worn by Return of the Jedi actor Lars Green. The latex mask with thick black fur left the stage for an impressive $22,705 - more than Mark Hamill (Luke Skywalker)'s contract sold for in 2007.
A TIE Fighter that really upset Darth Vader is our favourite piece however. If there's one Galactic Empire pilot in the Star Wars universe who doesn't get enough credit, it's the guy who accidentally bumps his TIE Fighter into Darth Vader's in Episode VI. In doing so, he knocks Vader out of the trench and allows Luke Skywalker to destroy the Death Star.
Grant McCune, head of the film's model shop, built just four TIE Fighter models for the production of Star Wars: A New Hope.
Little did he know that this model, built from resin around an aluminium frame, would one day become one of the most famous fighter ships in cinema history. The TIE fighter sold at a Hollywood auction in 2008 at around double its estimate at $350,000.
