Printed in rich color lithography on deep black paper, "Locus" from 1992 exemplifies Peter Alexander's sustained investigation into light as both subject and material. Working within a 76.2 by 78.7 centimeter sheet, Alexander conjures luminous passages that appear to radiate from within the surface itself, a quality that has defined his practice since his emergence from the Light and Space movement in Southern California. The black ground is not merely a backdrop but an active element, giving each chromatic gesture a quality of suspension, as though color exists somewhere between matter and atmosphere. Alexander trained at the Slade School of Fine Art and the University of Southern California, and his work has long occupied a distinctive position within West Coast abstraction, bridging the perceptual rigor of his peers with a distinctly lyrical sensibility. "Locus" reflects that balance with precision, the title itself suggesting a place of convergence, a site where light, color, and perception meet. As a work on paper, it demonstrates that Alexander's concerns translate fluidly across mediums, losing none of the spatial complexity associated with his better-known resin and acrylic works. Signed in pencil and presented as part of a numbered edition of 100, this lithograph offers collectors a rare and accessible point of entry into a body of work held in major institutional collections across the United States. Unframed, it presents an opportunity for thoughtful presentation suited to individual settings, and its measured dimensions make it highly versatile within both intimate and expansive interiors. Works by Alexander at this scale and in this condition represent enduring value within the market for postwar California abstraction.
