I have come across about 25 old charts from the 60's that are in very good condition. I have attached some samples. Most haven't been scanned yet, but the first high def sample scan looks pretty good. Is there any interest in copies? If so, i'll put together a list of what's available. There would be a small cost (maybe two to four dollars) to cover the scan cost. A good quality print will cost you about $40 at staples. I've seen a sample print, it looks very close to the original. You would get your own printing done. I'm not selling prints.
