This video claims that there are more than 20 million pieces of art in London's galleries.
The video is an attempt to see all the art in London in a single day. The protagonist in the video got to sample 13 galleries out of 92. The story reports the video's claim that:
Alex Gorosh visited 13 museums in London, saw more than 140,000 works of art, and walked more than 22 miles in one day in an attempt to see all the art there is to see in London. He didn’t even see more than one per cent of the art in the city. That’s because London has 92 museums, and more than 20 million works of art.
Is it true that there are more than 20 million works of art in London's galleries?
