This book is new and out of print and getting rare. Good time to buy it. as of today July 29, 2021 it sells for up to $902 on Amazon in paperback form...go look. Here it is sealed and ready for your library. (the picture I took on the inside is of a second personal copy I have) I will soon raise the price or listed, you guessed it on Amazon.
Please let me know if you have any questions.
