Crosby developed an obsessive fascination with imagery centering on the sun. His poetry and journals often focused on the sun, a symbol to him of perfection, enthusiasm, freedom, heat, and destruction. Crosby claimed to be a "sun worshiper in love with death." He often added a doodle of a "black sun" to his signature which also included an arrow, jutting upward from the "y" in Crosby's last name and aiming toward the center of the sun's circle: "a phallic thrust received by a welcoming erogenous zone."
