Queen Elizabeth II Barbie doll flies off the shelves PHOTO

A one-of-a-kind Barbie doll, never seen before, has sold out within just a few seconds of going on sale as toy lovers pounced.

A Barbie doll of the Queen to mark her Platinum Jubilee has sold out in just three seconds upon its release, news.com.au reports.

The Queen was recently immortalised as one of the iconic dolls to mark her 70 years on the throne.

But UK department store John Lewis said its stock of the GBP95 ($A168) doll sold out – seen as a key piece of royal memorabilia – in three seconds, with eBay sellers hoping to sell the sought-after collectible for a good profit.

The Queen Elizabeth II Barbie doll comes with an ivory gown and blue riband adorned with decorations of order – while her miniature tiara is based on Queen Mary’s Fringe Tiara – famously worn by the Queen on her wedding day.

Meanwhile, never-seen footage of the Queen throughout her life has been released in anticipation of a forthcoming documentary.
