„A few years ago, I had the good fortune of running across a first edition of Paul's textbook (not the recent reprint of the original text, but an actual 1948 edition). It was a real find. I bought the volume in an online auction for, if my recollection is correct, $35. Talk about consumer surplus! I would have gladly paid many times that.
At the next Boston Fed meeting, I took the book along to get Paul to sign it. Below is the book's title page, along with Paul's gracious inscription.“
