Andrew Wyeth’s Quart and a Half (1961) belongs to a deeply personal sequence of works inspired by a single day he and his wife, Betsy, spent picking blueberries in a field as a storm gathered. That afternoon became the genesis for one of Wyeth’s most iconic tempera paintings, "Distant Thunder" (1961), which depicts Betsy reclining in the grass with their dog, suffused with a charged stillness before the storm. A preparatory watercolor, Blueberries, Study for Distant Thunder (1961, Farnsworth Art Museum), further traces the theme. Quart and a Half marks the haunting aftermath, shifting focus from figure to still life: a blueberry carton and tin cup sit abandoned in the grass, their utilitarian presence transformed into emblems of memory and absence. 

The composition is stripped to essentials—a high horizon line, a darkened field, and the luminous carton and cup catching the eye. The disturbed grass, delicately rendered in intricate strokes, becomes a subtle index of Betsy’s earlier presence, now vanished. That empty imprint became the emotional core of the painting, an emblem of transience. As an early still life, the work reveals Wyeth’s ability to invest the simplest objects with profound emotional resonance, extending the still-life tradition, long associated with mortality and the ephemeral nature of life, into a meditation on the quiet echoes of lived experience. Executed in watercolor, the painting also highlights Wyeth’s balance of spontaneity and restraint, the flickering grasses animated with immediacy yet anchored by a deliberate compositional rigor. 

Quart and a Half also holds distinguished exhibition history. It was featured in the traveling retrospective "Andrew Wyeth: Temperas, Watercolors, Dry Brush, Drawings 1938 into 1966", shown at the Philadelphia Museum of Art, the Baltimore Museum of Art, and the Whitney Museum of American Art (1966–67). Earlier, the work was chosen as the cover image for the catalogue of the 1963 University of Arizona Art Gallery exhibition, underscoring its importance within Wyeth’s oeuvre. Together with "Distant Thunder" and its study, this watercolor transforms a shared picnic into an enduring meditation on memory, impermanence, and the poetry of everyday life.
