[Tagging] Billboards and other kinds of advert

[yarl at o2.pl]

I was searching for a tag for billboard and I don't see any tag for
advert. How about creating a proposal with something like this:

amenity=advert (or rather information=advert?)

advert=billboard

advert=board (sth like information=board, but for adverts)
advert=column (http://commons.wikimedia.org/wiki/File:Litfass2005.jpg)
advert=flag (http://commons.wikimedia.org/wiki/File:Flags_of_Gda%C5%84sk_University.jpg)

There is also one more but I don't know the name, in Poland it's
called 'citylight' (flat illuminated box, taller than wider):
