Lannisters vs Starks
This beautiful canvas art depicts two houses in two colours. The side with blue are the "House Starks", and the side with red are the "House Lannisters". This shows how they battled every time with each other because they had problems among their houses. behind the house members we can see their sigils are representing their houses. The side of Stark (the blue side) sigil is the the "Direwolf". And the side of Lannister (the side of red) sigil is the "Golden Lion". The families tolerated each other for a while, but that all changed once the Lannisters started murdering Starks. Tyrion Lannister could have an absolutely irresistible peace treaty up his sleeve.
