While visiting a Passau flea market in September, I cam across a great item for German beer aficionados. I purchased a brightly colored tin beer sign for my son. Later in Nuremberg, I found a great little shop across the street from the train station specializing in these metal beer signs made of tin. They feature various breweries and are quite attractive. I picked up two and brought them home to add to the Berliner Kindl sign I had purchased in Berlin way back in 1987. Below you can see all three hanging on the wall of my den.
Of course, you might want to hang them sparingly. Overdoing it will make your wall look like some kind of bar and your wife may not like it.
