Campaigners dressed as inspirational women from British history have gathered outside the Bank of England.
Caroline Criado-Perez, from Rutland, Leicestershire began a petition to see more women on notes after it was announced Sir Winston Churchill would replace Elizabeth Fry on the £5 note.
On Friday, she gathered with a group of supporters to "celebrate women".
Bank of England governor Mark Carney said he would look at women represented on the banknotes by the end of July.
'Celebrating' female figures
Some of the demonstrators dressed as suffragettes Emmeline Pankhurst and Emily Wilding Davison, as well as the warrior queen Boudicca and novelist George Eliot.
Ms Criado-Perez, 29, said: "It is about celebrating what fantastic women we have in our history and should be recognised.
"There are lots of women the Bank of England could choose from, it's not a difficult decision. Maybe they just need their eyes opened to what women have done in our history."
The campaign has already seen Ms Criado-Perez collect more than 30,000 signatures on a petition and gather £13,000 in donations to cover legal fees should the issue go to court.
Sir Mervyn King, the Bank of England's former governor, previously said there was a possibility that novelist Jane Austen could replace Charles Darwin on the £10 notes.
Earlier this month Mr Carney told the All Party Parliamentary Group for Women that those chosen should represent the diversity of great British historical figures.
