Just a reminder that the search continues for new examples of printed cancels on the documentary 1898 stamps. Our series on these cancels can be found here. The original organized attempt to list these cancels was orchestrated by Richard Fullerton in the early 1950s, and his list included express company cancels like the American Express example above. The list largely comprised the cancels of railroads, which utilized printed cancels on the documentaries more than other businesses.
