Hard to Find SCHWARZKOPF Shampoo Hair Care 1958 TM Black Enamel Pin brooch tack

This is a hard to find black enamel lapel pin with the Schwarzkopf (black head) profile logo in use by the inventor of modern day shampoo since 1898. This streamlined profile was registered in 1969. Until a commercial on TV this evening I listed this as a Van Cliburn profile. See last photo for resemblance. I have been unable to find any similar examples on-line, for Van Cliburn or Schwarzkopf. I see no marks but it may be a silver backing, but cannot confirm since the back is hard to read. Definately says Made in Germany. 3/4 inch in length
