These fascinating photographs of London in 1972 are a trippy flashback to life in the UK over 40 years ago. Appearing on Flickr in the collection of Glen F, they were apparently taken by an American tourist.

“I’ve found that Americans tend to take pics of ‘mundane’ things that us Brits would take for granted and never photograph, like the sandwiches! So you often end up with some unusual subjects showing regular everyday life,” Glen F shares.
