Since this activity spans all of firearms collecting I'm posting it here. I picked up a very nice J P Sauer Model 1913 32 auto pistol at the gunshow here last weekend. It's in exceptional condition or at least it was until the gun dealer plastered two price stickers right on the bluing.
I carefully removed the stickers this morning and they didn't come off easily and damaged the bluing underneath.

Hopefully any dealers on this forum will read this and take note.
As an aside: Whenever I put a gun up for sale at a show I use a hangtag on a string for the description and pricing.
