Set of manuscript transparancy architectural layout plans, by Percy Johnson-Marshall & Associates, at 1:1250 scale, with "letratone" areas numbered 2-6 (no 1 missing), showing the commercial area of the proposed comprehensive redevelopment of the University of Edinburgh campus. The first 4 show plans at different levels of the development - ground level, mezzanine storage level, deck level, and roof level. The final plan shows an elevation section through the development.

These plans are very fragile due to the stickiness caused by deterioration of the "letratone".
