From the hilarious and the moving to the downright furious, there was no shortage of brilliant signs at the Women’s Marches around the world on Saturday.

In recognition of the wit, wisdom and wrath carried on those placards – as well as the historical significance of the international Women’s March movement – museums and libraries in countries across the globe are collecting signs for posterity.

Organisations in several countries are creating a “living archive” from the Women’s Marches, according to a report by The Cut.

In the UK, almost 100,000 protestors turned out to the Women’s March on London to take a stand against Donald Trump’s presidency and forms of growing right-wing sentiment in general, including racism, homophobia and transphobia.

London’s Bishopsgate Institute – which houses cultural events, a library, historical archives and adult education courses – tweeted that they are collecting placards from the London march for their Protest and Campaigning archive.

The History Workshop in London is also asking women who took part in the march to send them their photos and stories from the day.

“We want the spirit of this historic day to be acknowledged and preserved, so we can continue to be inspired by this beautiful expression of grassroots democracy, peaceful protest and collaboration between all ages, faiths, sexualities and races,” said the History Workshop’s Hannah Elias.

Activist art often isn’t intended to end up in a museum, but preserving signs from demonstrations is a uniquely important task for modern historians. After all, few things capture the spirit of a particular moment in time quite like a protest.

Over at the Huffington Post, Katherine Brooks has collated a list of all the museums around the US and across the globe who are asking for sign donations, from California to Canada. You can check the full list out here.
