Despite visual distinctions denoting separate racial categories and social class status dividing father and son in From Spaniard and Black, Mulatto, how do visual cues connect them?

What will be an ideal response?

Answer: The ideal answer should include:
1. The father's vest matches the color of his son's jacket.
2. The father's body is bent forward toward his son, just as the son is bent toward his father.
3. The father's left hand joins his son's left hand to hold the brazier dish.
