Austrian school (XIX-XX), signed "Rosaspina" - Portrait der Wiener Moderne

Beautiful portrait of a woman from Viennese Modernism around 1900.

Oil on canvas, mounted on cardboard (marouflé).

Signed lower left "Rosaspina".

46.0 x 54.5 cm

Condition: needs cleaning; the cardboard is warped (since the painting is on canvas, the cardboard can be corrected without damage by applying weights).

Although the painting is signed by an artist named "Rosaspina", the influence of the Vienna School in style and color palette is so evident that I have localized it in Austria. I assume it was an Italian painter who lived in Vienna or worked there for a period.
