The New Union Flag, Gil Mualem-Doron, 2014.
Gil Mualem-Doron's show at Jubilee Library on Jubilee Street would have featured his work New Union Flag, which celebrates diversity and was created in collaboration with Stand Up to Racism.
It's created around the traditional crosses of St George, St Andrew and St Patrick, but it's also a patchwork of textiles representing dozens of other countries and cultures.
But Brighton and Hove City Council say libraries need to remain "neutral spaces and a safe space for all customers."
