The 00L Biosphere® IV celebrates Earth Day with a moving tribute to the emperor penguin and the fragile ecosystems it depends on. Artist Robert Goetzl’s custom artwork shows a parent shielding its chick from Antarctic wind, shaped by his belief that “when your environment is at threat, you feel very protective of your offspring… and the creatures around you that need protecting.” As part of this year’s release, Martin is proud to support the Globel Penguin Society with a generous donation toward its vital mission of protecting penguins, preserving critical coastal habitats, and advancing global education and stewardship. Crafted entirely from FSC®-certified woods, this sloped-shoulder 00 features sapele back and sides, a Sitka spruce top, and flamed maple binding. Play it, share its message, and help carry the call forward.
