The conquest of France in 1940 supplied the German forces with a hefty inventory of French-built sea mines. The Luftwaffe came up with a plan to drop them by parachute over Britain, not only on port facilities but on inland targets as well. They could be timed to explode at roof level, or to lie on the ground and then go off. See here and here.
Sylvia Townsend Warner has a short story "The Trumpet Shall Sound" about a funeral which would make a fantastic half-hour film with some unexpected CGI toward the end, and that's all I'm saying.
This 1982 West German five Deutsche Mark coin commemorating the 150th anniversary of Goethe's death reproduces the most important bit of the famous portrait Goethe in the Roman Campagna painted by Johann Tischbein around 1786. Working in a very constrained space the coin's designer is forced to suggest the contour of the great writer's hat and cloak with a notch beside his chin. But it also looks like an inverted speech bubble with the text outside and the picture of the speaker inside. The coin is from the online catalog of the Münzkabinett of the Staatliche Museen zu Berlin. See also.
