Welcome to my Wiki and Hobby!
These companies are researched and placed on this wiki when I find them referenced in advertisements from old magazines and newspapers. Information is found from primarily online sources including Newspapers.com and publications digitalized on Hathitrust.com. A primary focus of mine is manufacturing companies from the late-19th to mid-20th centuries.
It is important to note that while most information is trusted as true, some dates may be incorrect because of conflicting or faulty sources.
