Dienstbrief / official cover from the commerce raider SS Prinz Eitel Friedrich, interned in the then-neutral Norfolk News. Very scarce. With SMS Luchs Diesntsiegel / service cachet (scuttled in 1914). The Eitel Friederich had been part of the Luchs battlegroup, with a former Luchs officer becoming her commander upon conversion from passenger ship to commerce raider.
