A historical cartographic rendering displays the Texas oil and gas fields circa 1920, with hand-colored regions in cream, sage green, rust red, and deep blue marking geological zones and territorial boundaries. The aged parchment surface and intricate gridwork convey the methodical surveying of natural resources during the early petroleum boom era, layering geographic precision with the patina of time. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
