This is a note from Prinz Louis Ferdinand of Prussia to a sympathizer who sent his condolences on the death of his father, Kronprinz (later Pretender to Germany’s throne) Wilhelm (1882-1951). Prinz Louis Ferdinand (1907-1994) was the second son of Kronprinz Wilhelm and Kronprinzessin Cecilie. He became the eldest surviving son when his brother, Prinz Wilhelm (1906-1940) was killed in France during WW II while serving in the army. Prinz Louis Ferdinand became the Pretender to Germany’s throne when his father died in 1951. This card, which measures 4 1/8″ x 5 3/4,” is creme-colored and bordered in black. A printed message appears extending appreciation for the kind wishes expressed to the family. The card, from Bremen-Borgfeld, is dated 1951 (July) in the lower left corner. The card is boldly signed in black ink by Louis Ferdinand. It comes with its original mailing envelope, and is addressed to “Rittmeister a. D. Adolf von Lauff.” The envelope is bordered in black, and its inside is all black. The envelope was never mailed. Apparently, it was hand-delivered.
