Christine J. Gilbert's Photo I'm excited to share that my Superhero SG Logo was registered as a trademark with The United States of America Patent and Trademark Office. I did the registration myself. I have a children series, Super Grandma and Super Grandpa, The Unknown Superheroes, Book 1, 2, & 3. The characters on the cover of Book 3 are wearing t-shirts with the Superhero SG Logo. #2601741611629030221
