We may demand CGI-enhanced 3D experience from our Hollywood blockbusters, but our love for enchanting classics from the 20th Century still holds strong.

Which is why Coys, who specialise in selling classic cars, are holding their biggest ever poster and entertainment memorabilia sale at the Royal Horticultural Society in London December 2.

Featuring iconic posters including Casablanca, King Kong, Breakfast at Tiffany’s, Get Carter and James Bond, the firm are hoping buyers will see these classic movie posters as important investment potential.

Here are a few to take you back to a technicolour era when beautiful Audrey Hepburn and handsome Humphrey Bogart ruled the silver screen.
