New Brevoort Formspring

I live over in the UK, and Limited Edition Comix (a store that is fantastic) gets all its comics directly from the USA, so they arrive on a Thursday. Anyway, when Avengers #24 NOW came out, they had every variant, but not the one that came with Daniel Acuna's 50th anniversary poster. Is there any way I can get this? I've tried 3 separate stores, and it's such a nice poster!
