I just purchased a framed piece that I fell in love with the moment I saw it. I love the colors and the style of the artist. I know absolutely nothing about art but on the back of the piece is an older label from ArtLore. On the label it states that it is Grand Moulin by Paul Lecompte and under the artist' name it has Hand Colored Etching. It is signed on the bottom right. How old is this and is it an original or a copy? What would it's worth be? Where can I find similar pieces to add? Thank you for any help you may give!
