This is a genuine antique wax seal, red in colour and featuring a coat of arms. Un-researched but may be German or Bulgarian regional and 1700's or so as it was among others similar, but please see the scan to make your own mind up about this as I cannot offer any guarantee about provenance.
The scan is approx. life size and the seal which is on a scrap of a letter or other envelope is in good condition for its age and there is also a rubber stamp mark alongside it. There is some writing on the paper below the seal but I am unable to decipher this.
Please see others I am entering this week at reasonable cost. It would look great framed!
