That said, any oil painting really requires a physical appraisal by a qualified Fine Arts Appraiser. A local auction company should be able to refer one to you.
I have a picture by Robert Chaillous. The back reads: Winde Fine Prints; Still Life With Grapes; By Chaillous; no. 120 size 11x14. I picked it up at a yard sale. It's in good condition. Does it have any value. It's on canvas. Thanks
Re: Robert Chailloux
Based on the stamp and the description it's most likely a reproduction. Here's a link about the artist:
