The seal logo includes the Society’s Greek letters, motto (Sincerity, Truth, and Design), and symbols (the quill pen, the torch, and star). Together with the word mark, “Sigma Tau Delta, International English Honor Society,” a visual identity system has been developed to standardize our visual identity inside and outside the Sigma Tau Delta community.
Images are available in many formats. Instructions on appropriate typography and a set of complementary colors are also included. Should you need any other image formats or assistance with how to apply these graphics, please contact our Central Office at sigmaoffice@niu.edu.
