People often mock Donald Trump for having "small hands". This insult goes back to the 1980s, when Spy magazine dubbed Mr Trump a “short-fingered vulgarian”.

He allegedly got so angry about this that he sent photographs of his hands to editors decades later.

Perhaps because it seemed to anger him, the insult circulated the media and the internet, but no one seemed to know if it was really true, or whether it was a perspective trick.

The hand debate even entered the Republican primaries.

Marco Rubio mocked Donald Trump's hands at a rally."I'll admit it, he's taller than me," he told a crowd of supporters in Virginia.
