Old London! – Solution

The time on the clock of London’s famous Big Ben is different in the two photos reading some minutes past 10 in the first and a few minutes past four in the second photo. There is a plane flying in the skies on the right while it’s not present on the left.

You might have spotted the lamp post on the right-hand side of both photos, but the second image has the canopy missing on the top. Lastly, you can see the number ’12’ on the double-decker bus in the first photo, while the number on the bus in the second photo, although illegible, is different.
