This card was tucked inside the envelope that appears just below it. Written on the back of the card in an elegant hand: Pour Feliciter, arrividerci alle 6.
The envelope is addressed to Signor Antonio Zampieri, Guardiella no. 454, IIdo piano, Trieste.
(Note: "IIdo piano" may be translated as "second floor.")
On the reverse of the envelope is a gold-foil embossing of a man's profile, encircled by the name C. H. W. R. Gluck.
Catterina Fröhlich eventually married Antonio Zampieri. They had four children: Margherita, Giusto, Maria Pia, and Felice (born 1885).
Felice Zampieri became the father of Maria Zampieri Proni.
