This is an Austrian postal stationery card issued in 1888, bearing an imprinted 2 Kreuzer brown stamp featuring the double-headed imperial eagle. The text "Correspondenz-Karte / Carta di corrispondenza" reflects Austria-Hungary’s multilingual postal service, here in German and Italian. The card is postmarked and shows handwritten notes on the front, which appear to be mathematical calculations, likely scribbled during use.

On the reverse, a lengthy message in German script is dated 25 March 1888, written from Glarus, Switzerland (Ennetbühl/Steinthal region). The writer describes travel impressions, the alpine surroundings, and local conditions, giving the card historical and social value beyond philately.

Such early postal stationery is highly collectible, especially when used abroad (in this case Switzerland), with contemporary handwriting and clear postmarks.
