According to tree-ring data, a 4,853-year-old tree named Methuselah in eastern California could be the oldest on the planet. This customized mug features cross-section-inspired artwork to mark each year since your (or your favorite person's) birth. A celebration of life, every ring represents another adventure in a journey spent growing, gathering knowledge, and making memories. Artwork loosely based on the cross-section of a cottonwood tree, known for possessing a star shape at its center. Concentric tree ring graphics represent each year since a person's birth—the older* the recipient, the farther the arbor-like artwork will expand across the surface. Choose from one of five affirmational messages to appear on the mug. Each oversized vessel holds 15 oz. Uncommon Originals: Created by our in-house team and only available at Uncommon Goods. Designed and customized at Uncommon Goods in Brooklyn, NY. *We recommend gifting to recipients 18 years and older to enjoy the artwork's effect fully.
