Spotted this on my way home from work today.
Edited to add on 28/8/08: This poster was on Ducie St. There is also one on Station Approach (on the empty unit between CEX and Cafe Nero), and apparently one is also on Great Ancoats st (presumably on one of the many dereclict shopfronts).
That same poster will be up in 3 months time. Thats why every fixture for the next 3 months should be on it.
