Meanwhile I was working in Shell Chile, I was requested to reproduce a beautiful book where really master pieces were printed; at that time there were no massive computers nor electronic printers nor scanners, so I took a photo page to page, later I deliver my job but I kept negatives and many years later I found those negatives and decided to make new copies and scanned them to share, as I said before, these Master Pieces that are draws not photos. I do not intend to sell or make bussines with them but sharing them to be admired. Thanks.
