“Stop and admire this intimate portrait of Chicago collector Mary Block. Notice the artist's shift from avant-garde to a softer, Post-Impressionist style, capturing a serene and luminous presence.”
In this striking portrait, Mary Block, a prominent Chicago collector, gazes out with a calm, direct expression. Her figure fills the canvas, rendered with a soft, almost luminous quality that suggests a gentle inner light. The artist, Ivan Puni, painted her in a style that evokes the intimacy and muted tones of Post-Impressionism, a departure from his earlier avant-garde work. This painting was commissioned directly by Mary Block and her husband Leigh, highlighting their close relationship with artists and their dedication to supporting contemporary art. The work captures a moment of quiet dignity, reflecting the subject's thoughtful presence and the artist's mature style.

What to Notice
Four details hide in plain sight. Here’s where to look.

The subtle, almost glowing quality of Mary Block's skin.
The way her hands are clasped gently, resting on her lap.
The soft, diffused light that seems to emanate from within the painting.
The rich, yet understated, blue of her dress.
