Six different banners that stand to the right of the door at Lakeview Manor.
Redoran House
Telvanni House (not displayed anywhere else in game)
Dunmeri Temple 
Dawnguard
Imperial
Stormcloak

Only one can be displayed at a time, because they are in the same place.

If anyone has requests for different banners or the different houses, I'll be happy to do them.
