I can't find "F. Walter" in any of the artist databases we use but it's a nice painting and has decorative merit on its own, certainly.
Based on the photos and information provided, and subject to examination, this is:

Still life: vase with flowers
oil on canvas
30 by 25 inches
signed "F. Walter" lower left
CONDITION: appears to be in good condition
PROVENANCE: inherited
$300-500*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
