Gladys Kellogg was a "daring world traveler," according to granddaughter Kathy Fulton, and the shrunken head ("human or monkey, no one could tell") she brought back from a trip and passed down to her son bears this out.
She carried a "ladies bag" filled with modern items --- matches, bubble gum, etc. --- to trade for unique ethnic items, her granddaughter said. Some, like the shrunken head, were illegal to bring back.
"She was pretty determined," Fulton said. "If she wanted something, she wouldn't let anything stand in her way." [Link]
