A series of Brexit-themed posters were put up to haunt leading politicians with their own words.
One had Dr Liam Fox saying the Free Trade Agreement should be "the easiest in human history."
Another has Dominic Raab saying he didn't realise how dependent Britain was on the Dover-Calais route.
But it is now understood that at least some of the posters have already gone .
They were put up in various parts of Dover, the night before Theresa May narrowly saw off no a confidence motion in parliament by 325 votes to 306 yesterday.
The posters, with others put up nationwide. are by a group called Led By Donkeys and were first displayed in Stoke Newington, north London, on January 9.
The group said on Twitter: "We started a little project to record for posterity the prophetic words of our leaders."
Yesterday it said: "A busy night on the Brexit frontline. We’ve covered Dover in the historic quotes of the people responsible for this chaos."
The posters quote tweets from politicians about Brexit over the last few years.,
One is at the A2B Taxis car park at the junction of Dover's London Road and Cherry Tree Avenue.
It quotes Prime Minister May as saying in April, 2016: "Remaining a member of the European Union means we will be more secure from crime and terrorism."
A spokesman for A2B said today: "The posters were all around Dover but certainly the one next to us was taken down overnight."
Led by Donkeys yesterdays put out a tweet showing four posters put up in Dover, the fourth quoting arch-Brexiteer Jacob Rees-Mogg.
The tweet from Dr Fox, who is International Trade Secretary, was created in July 2017.
It read: "The Free Trade Agreement that we will do with the European Union should be one of the easiest in human history."
Instead there were months of wrangling with Mrs May making numerous trips to Brussels to negotiate with the EU late last year.
It culminated in the House of Commons rejecting the deal she brought back by a historic majority of 230. on Tuesday this week.
The tweet from Dominic Raab, from last November, said: "I hadn't quite understood the full extent of this but... we are particularly reliant on the Dover-Calais crossing."
A week later he announced his resignation as Brexit Secretary, saying he could not support the Prime Minister's proposals on the deal to leave the EU in March.
Mr Rees-Mogg's tweet, from way back in October 2011, said: "We could have two referendums. As it happens it might make more sense to have the second referendum after the renegotiation is completed."
