Hi guys I am looking for something and hope someone can help me.

adboards.jpg

I am looking for a pic of the back of the adboard, that one is from Benteler Arena but i know many other stads have those kinds of adboards.
What i wanna know is if the back of the adboard has ads too or is empty and also the structure of the adboard, I mean how does it stand.

If anybody finds a pic of that I'll be grateful.

Thanks
