Please Help Me Find The Set Of This Hamburger Sign in Archive - old v2 questions Posted December 20, 2016 All, thanks for your help so far. It might very well be from an Ideabook of some sort, I'm aware of that. I've also found out that the sticker is used in set 6399-1 To react to your question @thea: the color of all parts is red. I've searched with all separate parts to find out if any set might contain the sign, but unfortunately no positive result. I'll keep on searching and hope for some tips from the community.
