[cctalk] DEC Processor Books

I have often wondered about the people we find in the various DEC Processor (and other) books. Were they models in staged photo-sessions or were these candid shots from DEC facilities and if so, can anyone identify who they might be. Looking thru some of the books again I came across an interesting photo on page 42 of the 1981 pdp11 processor handbook / pdp11 04 24 34a 44 70. If you take a magnifier to the picture you will find the system presented in that photo is not a pdp11 but a VAX. :-) I wonder what other DEC systems are contained in these photos? bill
