I welcome comments and feedback, either in the comments fields of the relevant posts or via this contact form, and although the blog is written in English, please feel free to also contact me in German. Also, if you’d like to do a guest post about something you feel would fit well with the rest of the blog, please get in touch. So far I’ve been happy to host posts from Owney the Dog and Erin Blasco, from the Smithsonian National Postal Museum.
