6 copy plans (63cm x 127cm) by Percy Johnson-Marshall & Associates showing ideas for the surface treatment of the quadrangle at the University of Edinburgh Old College. The plans are all copied from 1 base plan at 1:100 scale, of which there is a paper blank. A series of different ideas are shown on the remainder of the plans through hand written additions and coloured letratone. 4 of the plans are transparencies.
