Plato Calendars is an imprint of BrownTrout Publishers, Inc. Plato Calendars is committed to sustainability. Our wall calendars are printed on Forestry Stewardship Council (FSC) certified paper from managed forests and are printed with soy- and vegetable-based inks, which are less harmful to the environment than petroleum based alternatives. We embrace a digital workflow to reduce paper use and recycle all overstock or out-of-date products.
