Paxton left his meeting with Henry Cole on 9 June 1850 fired with enthusiasm. He immediately went to Hyde Park, where he 'walked' the site earmarked for the Exhibition. Two days later, on 11 June, while attending a board meeting of the Midland Railway, Paxton made his original concept drawing, which he doodled onto a sheet of pink blotting paper. This rough sketch (now in the Victoria and Albert Museum) incorporated all the basic features of the finished building, and it is a mark of Paxton's ingenuity and industriousness that detailed plans, calculations and costings were ready to submit in less than two weeks.
