HENRY REGNERY COMPANY Publishers 114 West Illinois Street, Chicago, Illinois 60610 Telephone 527-3300 July 14, 1966 Dr. Ludwig von Mises 777 West End Avenue New York, New York 10025 Dear Dr. Mises: I have been meaning to write to you for some time, but the printer has been giving us so much difficulty that I did not know until today just when the book was going to come out. The month is now September. It's quite a de- lay compared to what we had originally thought, but I am satisfied now that the appearance of the pages is as near perfect as we can expect. I think you will remember that some time ago I requested that you return your set of page proofs. We do need the set for our files, and I would appreciate it if you would send it off in the near future. Thank you for all your help; I have enjoyed working with you. Very best wishes, Jacke Peterson
