Schan,
I did see the Proposition set on ebay a while ago (not sure if they are still there) but I never got them because their costs to ship to Australia where just ridiculous.
If I come across them again, will let you know.
Ari,
There are several in your post which are clearly MY posters. This is the last time I will remind you to send them on over.
Matt,
I recently got my RED DOG poster too. Bit uninspiring I reckon, but ah well whatcha gonna do!
