I'm in London tomorrow and I need a few posters for my room which I am re-decorating.
Just standard posters of random stuff ... bands ... maps ... celebrities ... flowers ... you know?
Are there any places that are reasonably priced (cheap) and have a large and wide selection? Preferably Oxford Street kind of area.
Please note this would obviously have to be somewhere open on a Sunday, around noon.
Cheers in advance!
