Shoreditch High Street will be projecting messages such as “Overturn the ideology of hetero male supremacy” and “sexual revolutionaries demand freedom from sexist gender roles” on July 27

On July 27 1967, the Sexual Offences Act made it possible for gay and bisexual men in England and Wales to have sexual relationship for the first time without being automatically criminalised.

Public artist Martin Firrell is marking this milestone in LGBQT with a commemorative project that stretches across the country on July 27.

With the support of human rights and social justice campaigner Peter Tatchell, he is taking over digital billboards and presenting key ideas in the history of the gay liberation movement.

Shoreditch High Street will be projecting messages such as: “Overturn the ideology of hetero male supremacy” and “sexual revolutionaries demand freedom from sexist gender roles”.

“No other human rights movement has seen so much progress in the space of 50 years,” says Firrell. “That is to be celebrated. And the activism that made that possible should be acknowledged. But there is always more to be done. How we think about gender now will liberate – or blight – people’s lives for the next 50 years.”
