I BRIEFLY checked the manga thread and didn't see it mentioned so I went ahead with a thread.
This week begins the 'new' year of JUMP as issue number 1 and to celebrate JUMP's 40 years of publication, they're doing something different this year with the spines. They're making a Dragonball-ish continuing image with the spines of each and every JUMP issue this year. And guess who is starting it off?
Luffy. Looks like he's eating some meat.
And if I'm not missing some crucial info somewhere, the ENTIRE FREAKING YEAR will be a giant OP image. What a great idea that makes JUMP a collectible item this year for foreign fans. Good luck collecting guys!
EDIT:
Fast-forward one year:
Well what a year it was. Thanks to the many people who contributed scans, pics, commentary, criticisms and pudding to what ultimately resulted in THIS as brought to us by brennen:
