Timeless icons deserve timeless frames. The skull and roses motif made famous by the Grateful Dead's 1971 "untitled" album (fondly referred to by fans as Skull and Roses) has endured as a Dead Head favorite since its introduction. Why? Because it struck a chord with the die-hards. Just like our Fort Knocks did. Elegantly balancing the dark and the delicate, this prescription pair will take you on a trip in a way only the Dead can.
