This item is in Excellent Used Condition. 
Used by a Dealer to hang on their store doors and behind counters to show that Puma Knives were sold there.  This particular sign, we think, was around 1970 or later.  This is the aluminum version. West Germany marking would indicate that it was made before the fall of the Berlin wall in 1989.  The Puma motto of Knifemakers to the World also came about this time period in the early 1970s.
This is a nice sign with minimal wear and lots of life still in it. The chain needs repair.
