The Montreal Museum of Fine Arts says an ad for its Picasso exhibit is back online – after being rejected for violating Facebook’s anti-nudity policy.

Spokeswoman Pascale Chasse says the advertisement was blocked because it showed Picasso’s painting “Femmes a la toilette,” which features two nude women.

Chasse said she found the situation funny at first – but eventually contacted Facebook after two different ads were rejected by the company’s ad-review algorithm.

She said the company has since put the original ad back online – and has promised to review its policies surrounding fine art.

A Facebook statement says the company is reviewing its advertising standards in light of the incident – and while its criteria doesn’t generally allow nudity in advertisements – it wants to make sure museums can share their most iconic paintings.
