Mr. Dieter Curths
Dear Mr. Curths
I am in receipt of a copy of a latter from Mr. Marx to you dated September 14, 1979. In that letter he refers to a Power of Attorney laut der Ihnen vorliegenden Vollmacht. Since I have never signed any Power of Attorney giving Mr. Marx authority to sign contracts on my behalf, I would appreciate receiving a copy (preferably a photo copy) of the Vollmacht to which Mr. Marx refers in that letter to you.
Thank you for your cooperation.
After receiving your reply I intend to write to you clarifying other publishing matters.
