5Anderson Design Group's National Parks calendar celebrates America's national parks with style. Inspired by vintage poster art from the late 1800s to the mid-1900s, these original posters spotlight great travel destinations and points of interest. Vibrant colors and well-crafted lettering add to the retro vibe of these posters. Printed with soy-based inks on FSC certified paper, this 12 x 12 wall calendar features large monthly grids that offer ample room for jotting notes, along with six bonus months of July through December of 2021. Also includes moon phases (CST), standard U.S. and international holidays.
