decor

I found this really old looking wall decor. It's wood, and it looks like an old bag of Stone Ground Grist Mill Flour. Not sure if the company is even real or not. It's even hand signed by the artist. I've posted it a few times on EBay and no one ever bids on it. Is it just a remake, or do people...

I came across this at an estate sale. I'm not sure if it's as old as it looks or not. It is signed by the artist on the back: C. Costa 92. Do you guys think this is 1892, 1992, or maybe even just a number of manufacture? Any info would help. I'm selling it on EBay without even knowing what it...
