This is probably a topical eBay find, but we're flagging up this Happy Mondays at the Hacienda Hillsborough Disaster Appeal poster because all the proceeds of the sale go to Marie Curie Cancer Care.
Which is definitely a good thing, as we've perhaps all known someone who has been affected by cancer in some way or another. As for the poster, it dates back to May 1989, is sized at 101cm x 75cm and is described as having 'a few drawing pin holes at the corners and a slight tear on the left hand side'. However, it would 'look great in a frame'.
Best of all, the starting price is just £2, so it isn't going to cost you a lot to do your bit for charity.
