The Baedecker guide I just bought of Hamburg looks like an old one. You can tell by the sophisticated picture on the front that resembles a landscape painting. Nobody prints guides like this anymore. Now they always have flashy photos, especially modernistic ones. This is the sort of thing Dora might be carrying if she sailed to Germany in 1935 on her first visit with Edward to participate in the activities associated with the Anglo-German Naval Treaty. Even if she flew back she might have actually sailed there even though it was an official visit. Either that or they could have offered tours of Hamburg and Bremerhaven — naval centers.
