On social media (Instagram, Facebook and Twitter) I am currently providing additional information about the history of department stores – the subject of my new non-fictional picture book ÉMILE IN BERLIN – MÄUSEHAGD IM WARENHAUS (‘Émile in Berlin – Mouse hunt at the Big Store’, Gerstenberg Verlag). If you are interested in where and which department stores existed and still exist, all of which were influenced by the Wertheim department store in Berlin (the location of my new book’s plot), then take a look!
