Thank you for all the kind comments. The book has been a 10 year project so I'm going to take a break from it. My wife will appreciate my not spending time on "the book". We have addressed envelopes nearly every day for the last three and a half years! Copies are in museums, universities and the collections of individuals in 47 countries.
This summer I'll evaluate alternatives that will make the information available in the future. Since publishing I have been documenting additional details that might be of interest to readers.
Again thank you for your kindness.
