An explosion of fun, colour and music hits Liverpool for this weekend's Pride festival. Quite fittingly, a vibrant piece of the city's history is now on display in The People's Republic gallery at the Museum of Liverpool, overlooking the Pride Festival's events at the Pier Head. This Rainbow Flag represents a very important first in Liverpool. It was flown above Liverpool Town Hall for the first time for the International Day Against Homophobia (IDAHO) on 17 May 2009. IDAHO marks the day in 1990 when the World Health Organisation took homosexuality off its list of mental illnesses. The flag is just one of the many objects that curators seek out to ensure contemporary issues and events in the city are represented for the future. You can see more photos of the flag on Flickr.
