For regulars to my website, you know that I publish a yearly newsletter chronicling the new information that I have found. I call it the "Great Lakes Dining Car Wagoneer"
For people who are not regulars, the purpose of the newsletter is to keep people up to date on my research, and hopefully get the word out that I am actively researching diners in the Great Lakes region. The newsletter has been published since 2003, and all back issues are available online.
This year, I have dedicated almost the entire issue to Ward & Dickinson.
Check it out! This link will bring you to my history page, and from there, it is only a click away. (In case you also want to check out old issues)
