Help - what is the origin of this sign?

[MaJo]

Hello , 

I need help identifying this sign I got from a heritage.

It's 65x65cm and has a tube on the backside for horizontal installation (rotation?). Maybe from Legoland or a Lego fair? 

Has anyone seen a sign like this?

I can't find it anywhere online 😕

Thanks for helping me out! I'm curious haha

You already got your answer of course (at 1000steine). But I'm wondering how did the heritage came about? Was the previous owner an AFOL or did (s)he have a shop? Must be a quite rare item. I loved those service packs back in the eighties as they were really good additions for the LEGO 12V trains.

Thanks for your answer ! He collected several things, including big illuminated signs like this. But this one was the only Lego sign. 

Very interesting! I was born 1996 so I missed out on that haha
