John Wick or Material Objects as a Means of Portraying Characters’ Personality

So, I saw John Wick some days ago. It seems he likes architecture. In this picture we see Alvaro Siza on par with an Armani Lambskin Jacket or a 1969 Ford Mustang Mach 1 as symbol represented by the book Alvaro Siza, Complete Works 1952-2013. So, judging by some adjectives extracted from Alvaro Siza's wikipedia page, John Wick, the character is european, renowned, unobstructed, reconstructed, poetic, giving, cultural, accessible, honored, special, natural and complex.
