FACEBOOK users couldn’t believe their eyes when a person listed what appears to be giant lamps for sale on Marketplace.
But look more closely, and you’ll realise all is not what it seems.
From the angle of the photo, the lamps look like two massive grey clocktower bells sat on the grass.
“That’s one of the most convincing illusions I’ve seen in a while,” one user said.
“Took me long enough to figure out.”
Another admitted: “I’m at work staring at this like an idiot – just figured it out.”
A third baffled viewer added: “I don’t think I would have ever got it, I just accepted they were huge.”
In reality, the lamps are ordinarily small.
If you look above, you’ll notice that they’re actually hanging on a wire.
Because they’re photographed close up, and with the angle of the garden grass, it just makes the lamps appear huge.
