MvR artifacts

[Biber]

In his description of a "crusher" visor cap that he is selling, Ken Greenfield (http://www.derrittmeister.com/justin.htm[/URL] ) mentions having held one of von Richthoven's "crushers" -"I once had the privilege of holding in my hands one of von Richthofen’s 'crushers'. At first glance it was not very impressive; it looked like a rolled-up gray rag. As you examined it more closely, the black visor became visible (pretty well crushed too)! Then inside the liner was his signature." - So what other such Richthofen artifacts are out and about, other than the usual items associated with his downing/death?
