What do you see?

An optical illusion has sent social media into a frenzy with thousands struggling to work out the image.

Savannah Root from Lamar, Missouri, shared the black drawing on Facebook last week and since then the image has received 26,000 likes, 4,500 shares and nearly 9,000 comments.

In the post, she wrote: 'I stared at this picture for an hour trying to figure out what it was.'

She then invited others to post below about what they thought the image represented.

While some managed to spot the hidden silhouette of a cowboy straight away, many were left entirely stumped and thought the painting looked like a bat.

More obscure suggestions included a rat hanging upside down with wings, a bird carrying a baby and a penguin doing a wee.
