Synchronicity rules. In the secondhand book market under the South Bank end of Waterloo Bridge, I found a book of American Indian Antiques - specifically Eastern Woodlands! It was just a few minutes between a London shopping trip and a sudden storm, and there it was. Photos of dress and artifacts, as specifically requested. Also a book of American recipes including chapters of Indian food, divided by geographic groupings, but I couldn't afford that as well. Current idea for plot, which already includes a crew member being reprimanded for jumping to conclusions about the Indians intentions, is for the Indians to offer food to the crew.
