Oscar created a tree to honor his grandmother, Modesta, who died in 1987. This prizewinning sculpture features a figure of Modesta, sitting in a chair painting a tiny mermaid figure. The rest of the tree has small scale representations of typical Mexican handcrafts including a miniature Tree of Life. It is to represent what she began making, which at first were whistles and piggy banks. He was also commissioned for sculptures by John Paul II .
