I feel a kinship to Osborne Witherspoon in this story from Startling Comics #45 (1947). Osborne is feeling his age. Me too. There are days when I creak like a rusty gate. I could use a charm to feel younger, like old Witherspoon gets from a Native American.
Fighting Yank, aka Bruce Carter, is guided by an old spirit, the ghost of his ancestor, who fought in the Revolutionary War. Bruce is no stranger to old people.
