Eddie Martinez is in their artist list. You have to go to "see more artists". The editions on the site are the ones from last year. The new ones are not even on the site yet. They will be soon. So if you want to have first access to them you have to contact them directly.
The unique pieces all sold out within a day. There were only 6 available. However the 2 new editions should be still available.
I learned about this via instagram and emailed them to find out.
