In March of 1926, three employees at the Washington Co-Operative Egg & Poultry Association Headquarters, (left to right) Mary Zack, Sarah Gruno and Esther Christoferson, demonstrated how to decorate Easter eggs. Sarah Gruno, in the center, is dyeing eggs with natural dyes made from vegetables, such as beets, spinach and coffee. Mary Zack is cutting out transfers to decorate her eggs, and Esther Christoferson is using a pen and ink to draw faces on her's. The Washington Co-Op packed transfer pictures with every carton of eggs sold around the holidays.
