Finally!! I have my first Mondo poster being shipped to me and an Olly Moss poster at that. I didn't get the dreaded "Sold-out!" message and I should be receiving Moss's awesome "The Dark Knight Rises" poster in a couple of weeks.
Props to Mondo for trialling a time based release for the poster or I never would have been able to order one. Instead of a set limit, Mondo allowed as many purchases of the poster to be made in a set amount of time and the number sold at the end would be the edition limit which wound up being 9350.
I really hope Mondo continues with this purchase model for future poster releases.
