Profiles in History's California auction, featuring Hollywood A-lister Megan Fox's leather costume and an 18-feet robot, made $5m last weekend.

The sale was remarkable for the sheer size of some of the lots on offer. A full-scale "Hero Bumblebee robot" from the blockbuster hit Transformers brought $88,500.

Another menacing Hollywood robot fell just behind the Bumblebee, bringing $70,800 - an original full-scale T-800 endoskeleton from the Arnold Schwarzenegger-starring Terminator 3: Rise of the Machines.

Meanwhile, Megan Fox's "Hero Black Leather Motorcycle Costume" - worn as her character Mikaela Banes, in the Transformers sequel Revenge of the Fallen - fell within its $3,000-5,000 estimate, selling for $4,130.

Smaller iconic items included Elvis Presley's personal Martin D-28 guitar, used in his final Las Vegas performance.

The King's guitar sold for $106,200, while Michael Jackson's light-illuminated glove from his 1984 Victory tour brought $70,800.

Elsewhere, an original Stormtrooper helmet from the groundbreaking 1977 blockbuster Star Wars sold for $82,600.

A rare and historic piece of non-Hollywood memorabilia also sold in the auction. Legendary explorer Amelia Earhart's flight goggles, worn during her historic 1932 solo transatlantic flight, brought $141,600.
