I am not an art expert. The first painting my wife and I bought was a signed/numbered lithograph by Sandu Liberman that we bought at a cruise ship art auction. We overpaid! But we loved the painting anyway. One day while I was at a thrift store hunting for books, I found a nice signed/numbered flower print. I wasn’t really looking for paintings, but it just jumped out at me. I bought it for $15. A few days later I found a Sandu Liberman print at another thrift store, and I bought it for $10. This was much cheaper than the print we bought on the cruise ship. Since then I have started checking out the paintings. I am still learning. I have gotten better in being able to tell an original from a print. I am having fun learning, and buy what I like or seems interesting. I am enjoying the hunt!
