She signs her work "Hashi." Exceptions are rare and when they occur, they occur with reason, Hashi's reason. She once said, "Most people probably never think twice about what they are doing when they sign a check, a letter, or whatever, but for me, signing, especially my drawings, is an excruciating task. For a long time, I left my work unsigned. I wanted to remain anonymous, unknown, left alone. Then someone convinced me that my drawings were unique; only I could have created them. I no longer seeked to be alone."
