Theyer & Hardtmuth Envelope with Embossed Crest Armory c. 1860s

For your consideration is one envelope from Theyer & Hardtmuth, a stationery shop in Vienna. The envelope likely dates back to the 1860s and is from an Austrian aristocratic family.

A very rare find indeed. The raised crest is a true work of art. Look closely. 

Envelope: 4.75" x 3.75"
