This color-cut puzzle is quite large and was challenging. The streaks are due to sunlight; I didn't notice them when I took the picture. When I received it, there was a section of pieces missing and there was one replacement piece in the upper right hand corner that was well cut, but poorly colored. I re-made the missing section and because I liked this puzzle, I took it to a professional conservator for the artwork. It turned out to be quite expensive. I was happy with the results but I don't think I would use their services again unless the puzzle was very valuable.
