Has Esther been stealing LibDem posters?

Having been directed to this ITV News report from Strange Thoughts, I was intrigued to to see the final shot of the film which was of Esther putting up one of her own campaign posters in a shop window. However in the pile of her posters behind her was clearly a Liberal Democrat poster for our candidate there, Qurban Hussain!

 Something fishy?

Has Esther been "liberating" LibDem posters?
To be fair, it is also possible that this is an example of TV fakery and they probably found a shop window which already has a LibDem poster in but took it down as it would have ruined the story they were trying to tell. But did they put it back? Or was it just there in the middle of Esther's pile?

Enquiring minds need to know!
