Did you experience any “aha” moments?

Opening the door to some of the bathrooms in the book just made me gasp. I often thought: I’m so glad I have a camera, because I could never describe this for anyone. But the biggest “aha” moment came when I was looking in a book and saw an ad for bathroom fixtures from the 1920s. The illustration of the bathroom looked just like my bathroom. It seemed like time had stopped for a century.
