Harper & Row, 1966. Black cloth bound hardcover with dust jacket of the business classic The Effective Executive by Peter F. Drucker.
This appears to be an undated 1987 reprint of the 1966 edition based on the Harper & Row logo to the front cover's cloth, which dates to when Harper & Row was acquired by The News Corporation.
"Mr. Drucker identifies five habits or practices as essential to effectiveness, and these can be learned."
Fine. Nice crisp copy with clean, bright interior pages.
