Now The Crown, the acclaimed Netflix show about the royal family has finished, the detailed sets costumes and props are being sold off by auction house Bonhams next month.
Sought-after items including Princess Diana's infamous black "revenge dress" - or the recreation of it at least - as well as the blue swimsuit she wore on a yacht with boyfriend Dodi Fayed are among the lots.
Here are some of the items going under the hammer.
This outfit was worn by Imelda Staunton when she played Queen Elizabeth II and was inspired by the real outfit the monarch wore.
Seen in season 6, episode 5, the coat, dress and hat are accompanied by a broach and earrings.
An original black leather Jubilee Launer handbag - always seen in the Queen's hand - completes the look.
It's set to fetch $2800-$3800.
It's the dress that's said to have revived the now Prince of Wales' interest in a student Kate Middleton.
A recreation of the dress she wore at a charity fashion show featured in the final season of the show.
It was worn by actress Meg Bellamy.
It's set to go for $3800-$5700.
It was worn by Princess Diana just days before she died and this recreated swimsuit, cap and jacket outfit could fetch up to $2300.
It's the aqua number worn by Elizabeth Debicki as Princess Diana when she was on Fayed's yacht.

This car portrayed the late Princess Diana's personal Jaguar XJ-S Cabriolet in The Crown.
Set to fetch $28,000-$37,000, only 5000 of the cars were made.
It's one of the most famous rings in the world, and it's now on the finger of the Princess of Wales.
First seen in the The Crown's engagement scene, and throughout season 4, it is inspired by Princess Diana's engagement ring made by London jewellers Garrard & Co.
It features a halo of cubic zirconia around an oval simulated sapphire central stone, set in silver-coloured mounts.
Despite not even being a real gem, it could go for more than $5000.
One of the renowned frocks in the world, The Crown's version of the "revenge dress" worn by Princess Diana is up for grabs.
The custom-made off-the-shoulder pleated black silk and chiffon cocktail dress with mini chiffon train, together with black satin pointed sling-back shoes, and a black silk and velvet envelope clutch bag, could fetch $15,000-$23,000.
Diana wore the original, designed by Christina Stambolian, to a Vanity Fair party at the Serpentine Gallery in London on November 20, 1994, the day that Charles' affair with Camilla Parker Bowles had gone public.

The Queen Mother famously loved a tipple, and this silver-plated drinks tray together with all the props needed to fix a nightcap was created by set decorators for the show.
It could fetch $150.
John Lithgow played Prime Minister Winston Churchill, and props made for him included a vintage bowler hat made by Cosprops, a wool and silk paisley printed scarf made by Turnbull & Asser and two pairs of spectacles made by C. W. Dixley & Son, with faux tortoiseshell frames.
The set could fetch $1100.
The late Queen Elizabeth II loved her corgis, and these items were used to decorate her desk.
The two Beswick porcelain corgis were sourced by the set decorating department for Season 1 based on archival research which revealed an image of Queen Elizabeth II with similar pieces at Windsor Castle.
They could sell, along with a framed photo of one of the dogs, for between $380 and $570.
Gillian Anderson portaged Prime Minister Margaret Thatcher in the show, and wore this suit, pussy bow blouse and Ferragamo shoes.
The outfit could sell for $2800-$3800.
One of the most lavish props made was a reproduction of the Gold State Coach.
Seen in episodes in both series three and six, it was inspired by the 1760 commission by Francis Rawdon-Hastings, 1st Marquess of Hastings for King George III, and designed by Sir William Chambers.
The TV replica was created by The Devil's Horsemen, who built the chassis, and Anarchy Ltd, who were responsible for the body.
A collector who buys it will likely have to splash out between $57,000 and $95,000.
A rather unusual piece, somebody could take home this replica of 10 Downing Street, the official home of the UK prime minister.
The facades of numbers 10 and 11 Downing Street were recreated faithfully to scale at Elstree Studios in London.
The door of No.10 had to be scaled up during the first two seasons when John Lithgow played Winston Churchill.
The actor was considerably taller than Churchill and so to ensure the realism of the scenes, the decision was made to make it bigger too.
The collection of sets could go from $38,000 to $57,000.
