Can anyone help me find this poster?

[WhitesAndStripes]

I am trying to get hold of this poster from the London 2012 Olympic games, but can't find one anywhere. Literally nothing on Ebay or anywhere else - it's almost like they never existed, because I can find most of the other ones that were available at the time but not this one. I was wondering if any of the excellent MN sleuths might know of any sites selling 2012 posters etc.

Just adding this to say that I don't think it was one of the ones done by the big name artists like Tracey Emin, Bridget Riley etc, I think it was the bog standard poster. I can find ones by the big names but just not this one which is odd as I think it was the most produced one (i.e. not limited edition).

I found a framed one from an old auction. Only helpful in as much as you didn’t dream them and they did exist

I was beginning to wonder if I imagined them!
