As part of his bid to retain the Labour leadership, Jeremy Corbyn held a rally in the left-wing stronghold of Liverpool last night.
Estimates put the number of attendees at 5,000, a sizeable number, but not exactly the crowds depicted in this tweet.
The post, and other similar posts, were tweeted by numerous Corbynistas, decrying the lack of coverage by mainstream media using the hashtag #Wearehismedia.
The images are actually from the 2005 Champions League winners parade, where Liverpool players rode through the city on a double-decker bus.
The awkward social media mishap, as usual, sparked a flurry of mickey-taking tweets.
Here's the actual scene, from Corbyn's own fingertips.
