A huge rush has started among fans of the famous films, as toy chain Toys R Us has put some unique artwork under the hammer.
The memorabilia was used to promote toys from The Clone Wars, the latest release in the Star Wars series.
On offer are life-size figures of leading characters from the film, with all proceeds going to Great Ormond Street Children's Hospital.
The cutouts include a four foot tall Yoda, Master Jedi and Luke Skywalker's mentor, and a replica of Anakin Skywalker, Luke's father, that stands more than six feet high.
Long queues of Darth Vader devotees are set to build up at the superstore, in Birstall, before the first bid is made.
A recent midnight opening attracted dozens of fans – and that was just so they could be among the first to buy the toys attached to the film.
Oliver Waterland, multi-media manager at Toys R Us Leeds, said: "In the past I think they were just thrown out, so this is a way to re-use them and raise some money for a really good cause. It is hard to say what they could go for, because people are so passionate about Star Wars.
"It is a series that has real hardcore fans and this artwork is real collectors' stuff."
James Burns, of Star Wars site Jedi News, said items such as the Toys R Us wall displays are always at the top of the target list for fans and collectors.
He said: "For the first time, fans have a great opportunity to add The Clone Wars displays from the Toys R Us feature wall to their own collections.
As they will be raising money for such a worthy charity at the same time, it's a win-win situation for all."
The store opens at 10.30am and the first lot will go on sale immediately.
Similar events will be held at the other 72 shops in the UK chain.
