I'm doing research on a woman who traveled through Italy, German, and the U.S. in the 1910s and 1920s. She uses a Baedeker guide as an analogy. I'd love to have a sample Baedeker like the ones she might have seen / used at that time for those countries. Short of looking on eBay, where else might I find one? Did Baedekers really change over time? Were they always red?
