Hi I.Q.

Cut in 1950's by Par Company, New York, NY, interlocking with 2 figure pieces, the Par seahorses. Par time: 8:00. Pictorial map of Cambridge University, in Cambridge, England. Displayed around the border are pictures and names of famous graduates of the University. One piece was missing in the border, and to accurately do the lettering required hours of research, by Alden Vaughan, Worcester, MA, retired Columbia U. history professor, and myself. I think we figured out the appropriate names!  800 pieces, not 750 as stated on box label.  Extremely difficult.  Par also published another puzzle titled "Hi I.Q." made from a pictorial map of Oxford, Cambridge's rival.
