Antique Sattler Richter & Co. Chicago Illinois jewelry store badge, tag, plaque or name plate circa 1900.  Company was located in Chicago, Illinois .  I believe it is made of brass.  Size is approximately 5 13/16" x 3/4".  I believe this was a jewelry store located at 212 market 4th floor with the owner or president as Felix Sattler.  I found a listing for a Felix Sattler who was born in 1872 Paris France, and death in 1938 Chicago Illinois that could possibly be this person.
