Vintage Barbie dolls are fetching thousands of dollars online amid a craze surrounding the highly-anticipated blockbuster film this July.
Barbie dolls have become a collector's item in the decades of production by toy maker Mattel since the first doll debuted in 1959.
The dolls can attract eye-watering price tags with extra value for mint condition and rare editions.
A pre-owned 1959 Barbie doll is listed for $9000 on eBay by a seller in Melbourne.
While a Barbie released to celebrate Queen Elizabeth II's Platinum Jubilee is listed by various US sellers for between $1000 and $7500.
More recent Barbie releases still in their box are on offer for hundreds of dollars.
