The PAAA is a political organisation not connected to any specific political party.
The image chosen for the billboard campaign is a concerned, and presumably highly stressed, May leaving Downing Street.
It was taken the morning after the attack on Westminster, which took place on 22 March.
Original caption: Prime Minister Theresa May leaves Downing Street on March 23, 2017 in London, England. The British Prime Minister Theresa May spoke last night after a terrorist attack took place in Westminster, saying Parliament would meet as normal today and "We will come together as normal". PC Keith Palmer and three others lost their lives in the attack and the perpetrator was shot dead by police.
Asked if the context of the image was known to the PAAA when they launched the billboard campaign, Sam Fairbairn, the National Secretary of the People’s Assembly told indy100:
This is a stock image of Theresa May its choice has no wider significance.
The PAAA did not respond to further requests for comment from indy100.
On the crowd funding website created for the campaign, the PAAA says:
The People's Assembly has launched a nationwide billboard campaign in the run up to the election accusing Theresa May of being a 'threat' to our public services.
We've put up over 40 of these across the country but we've now used up every penny we have! We want to do more billboards, adverts and actions across the country to expose the truth of Tory policies. We're taking back space that's usually only reserved for the big business and corporations.
According to a spread sheet available on their website, the first seven billboards were put up on 21 May, followed by more on each day until the last was erected on 26 May in Carlisle.
The Daily Mirrorreports that the first 40 billboards cost £65,000 and were funded by a single donor 'Alexander Wright'.
Details of his identity were not given to the Mirror, and there are no further details available from the Electoral Commission at this time.
The assembly is now crowd funding for further billboards.
The fundraising target for a new set of billboards is £50,000, of which more than half has already been pledged by donors.

On Friday, the Nottingham Post reported that a separately funded billboard has been put up in Nottingham.
The £2,000 crowd funding campaign was carried out by a local branch of the PAAA.
