A mask Lady Gaga wore in her Manifesto of Little Monsters short film is among the highlights in PFC Auctions' online sale, which closes on October 1.

It carries a starting bid of £750 ($1,225).

Franc Fernandez, designer of the meat suit, created the mask

Franc Fernandez, also responsible for the infamous meat suit, was behind the lot's design.

The singer's costumes hardly ever appear on the market, a trend she addressed in a recent interview with Harper's Bazaar.

"The fashion I've acquired over the years is so sacred to me - from costumes to couture, high fashion to punk wear I've collected from my secret international hot spots...I keep everything in an enormous archive in Hollywood," she said.

Those rare pieces that do come up for auction tend to sell well, as illustrated by the recent $31,250 auction of an angular photo-shoot dress.

The present lot could well prove a strong investment as demand for her memorabilia grows.
