Antique guache watercolor alpine Austrian german swiss mountain scene painting

Antique guache watercolor alpine Austrian german swiss mountain scene painting signed f. frankhauser. not perfect The matting had water damage and there is a dark spot on the painting. I took this and it's partner painting dated 1901 also listed in my closet to a local art director and I was told it could easily be cleaned and rematted but she cannot take any more restorations right now. so I'm pricing lower.
