They're releasing links to websites with the posters little-by-little via their twitter feed.

They just sent out the link to a NY times blog post with more posters:

Just an fyi/warning... Mondo posters are (to my knowledge)
only sold online, are very limited in quantity, and sell out
within a minute once that tweet of "ON SALE" goes out. You'll usually find them later in eBay selling for obscene amounts of cash.
.......Actually, I just did a search, and they're already for sale in eBay for up to $225!!!! They haven't even been sold yet!!! ... not sure how someone can sell things that aren't yet available to the public......
Also, for any folk in Austin, they have a kids event on Saturday morning to view the artwork:
