Too modern for an antique venue? No, not really, considering my art history life-long and college education. While it's been framed in a modern frame which seems to me not to suit it well, this c.1910-30 French oil painting on stretched linen canvas is just superb, and an example of the departure from Expressionism to Fauvism. The differences remain arguable, and Matisse and others moved between the two movements. Dufy is an artist more thought of as Fauvist, and Braque. You'll want to study the movements a bit more on your own. The unsigned but wonderful old French oil painting begs to have a different frame. Taken on its own, the painting is rich is color, form, surface treatment. I admit I can't decide if this is a dog or a cat, but closing in on the shapes of the painting makes it of little concern, doesn't it. Perhaps that is part of the point - Is it this? Or is it that? Full measurements are noted on the photos. I found the painting in France.
Very good to excellent condition on the very old French linen canvas and it's stretcher frame. I see nothing to report by way of flaw or loss, though I can see from the backside there is a small spot which has a mend from backside (white patch) which is impossible to find on the painting as a corresponding touch up. Fine age to the canvas and stretcher frame, and it appears the artist has signed on the stretcher (see images), but I can't make out the name. As noted, the frame is a modern or quite new vintage frame, wood with a gold wood filet. I think, were I to keep this painting, it really needs to be framed more to the aesthetic. Really, I'd even lean to just brush-painting it in a warm gray tone or even gold if you intend to keep this frame. Just the artist in me (and art historian).
