Not actually a mural as such, but I like these posters from the current series of events in Manchester which support Russia's LGBT community. I played around with the President Putin poster to create my own mural- feel free to share! Taking part in Monday Mural.
The events, which run during the Sochi Winter Olympics started with Friday's demonstration in Manchester, where thousands gathered as the Sochi Winter Olympics opening ceremony started. See the report and great photography from Friday night's demo here and here.
