I love the idea of symbols for different groups.
the white tree for gondor
the white horse for rohan
the red eye for mordor
the white hand of isenguard
but there were several factions where you didn't see any symbols. standards in any of the films. If so what would they be.
Here are some factions we don't see with a symbol give me some suggestions for them(or even better some art)
Hobbits of the shire (malitia)
the dunedine rangers
the dwarves of erabor
the dwarves of the iron hills
the dwarves of moria
the evleves of rivendale
the elves of lorien
the elves of the greenwood
the easterlings.
Perhaps if we get good art work we can ask for it to be part of some merchandise at some point, who knows but its an interesting idea.
Dunedain Rangers
and Elves of Rivendell

Earendil had two
The elves of Lothlorien would probably be bearing a silver tree with golden and green leaves, a Mallorn. I'll post a picture of a Mallorn I'm drawing later. They were based off birch trees, keep in mind.
Well there is also half-moon of Morgul
Hobbit Shirriffs bear a feather in their caps.
