If you are like me you try to make it a point to collect all things Oda and One Piece related. I don't care to collect SJ magazine on a monthly basis because the only series I really care about in there is OP and I know I am going to get the chapters when they come out in the volumes anyway. However, some SJ magazines come with special One Piece content that we may never get another official release of again - this thread is about listing these magazines down and hunting them accordingly. The two that I own are…
SJ Dec 2009 - Containing one of Oda's Romance Dawn one shots.
!
SJ March 2011 - Contains Oda's collaborative effort with Toriyama, the Cross Epoch which has both DB and OP characters.

If there are more like them - list em below.
