Through the purchase of our Great Lakes Postcard Mosaic packets, you are supporting the conservation of the the largest freshwater lakes on our planet. Each packet includes twelve 5" x 7" color postcards designed by the artists participating in the Water Worlds Exhibition, June 10th - 30th, 2022, at the Anchor Building Gallery in Saint Clair Shores, Michigan. The cards have been designed to fit together as a mosaic map of the five Great Lakes. The cover card shows the complete mosaic design and the backs are blank and can be used as notecards. The proceeds from the sale of these postcards will benefit the Alliance for the Great Lakes, an environmental organization dedicated to protecting the Great Lakes, North America's inland seas.
