About the Heartagram
The heartagram is the trademarked symbol of HIM, best described as a combination of a heart and an inverted pentagram (love & hate), created by Ville Valo the day of his twentieth birthday. Valo has said that "the heartagram stands for HIM as a band, as an entity, and for 'love metal' in general."
Many fans of the band have heartagram tattoos, or tattoos of other HIM emblems - such as the single heart on Valo's right wrist, and a number of fan-submitted photos of same decorated the lyric booklet for the limited edition of Dark Light.
Ville Valo has allowed his close friend, Jackass star, actor, and professional skateboarder, Bam Margera to share the license on the heartagram image and Margera has accordingly used it for his promotional purposes, including using it on his Adio shoes and Element skateboards. Because of the shared license, the symbol is often thought to belong solely to Margera. According to Valo, the band has become better known for their logo than their music.
In a video interview, Ville has stated that the Heartagram is a "Modern Yin Yang," the heart being the Yin and the inverted pentacle being the Yang.
