I collect mail sent from Frankfurt am Main during its independence as a City State. The stampless cover illustrated here is new to my collection. The address is in French. I’m not proficient in French and cannot fully read what’s written on it. It is addressed to Johann Eustach, Count von Goertz. (1737-1821) He was Prussia’s representative to Reichstag at Regensburg from 1788 to 1806. Can you translate the address?
"À son Excellence, Monsieur le Comte des Goertz, Grand-croix des ordres d.. M. le Roi de Saxe, son chambellan Conseiller, intime actuel et ancien minittre"
