Grateful Dead Unisex T-Shirt: Truckin’ Skellies – Eternal Groove Edition Keep on truckin’, eternally. This black soft-style cotton tee immortalizes the Grateful Dead’s trippiest tradition with a vintage-style lineup of dancing skeletons mid-stride—carefree, coordinated, and wonderfully undead. Arched above in rainbow-distressed font, the Grateful Dead stamp crowns this piece with acid-washed nostalgia. Cut for comfort with short sleeves and a unisex fit, it’s a tribute to movement, music, and myth—a wearable slice of counterculture history.
