AS NAGUIB MAHFOUZ enters his 93rd year celebrations abound. All of which brings to mind a singular Al-Ahram party, held more than four decades before by the then Editor-in-Chief Mohamed Hassanein Heikal to mark Mahfouz's 50th birthday. Among the guests were the most prominent cultural figures of the day. Here Mahfouz is pictured with author Tawfik El-Hakim and singer Umm Kulthoum.
