In the '60's last century I did art on leather clothing with a wood burner and acrylics. As signing my name with a burner was ugly and stars appeared in many if not all my work those days the women I was arting for, Juice and TieDie, suggested I make a sigil of a B and a star.
They then advertised art by Bobby * and the die was cast. I spell it bobbystahr as it seemed pretentious as I'm a musician as well, without the 'h'.
