A vibrant and energetic oil on canvas, Grace Hartigan's *Trick or Treat* bursts with the bold, gestural brushwork characteristic of her Abstract Expressionist style. The work evokes the chaotic festivity of Halloween through dynamic color and form, blending figuration and abstraction in a way that captures both the playfulness and underlying eeriness of the holiday. Hartigan's expressive marks and layered paint surface reflect her signature approach of drawing from everyday American culture and transforming it into raw, visceral imagery.
