I wonder if any of your readers can give me information about a special envelope which was flown by a hot-air balloon in York on September 2, 1981?

This flight was part of the celebrations of the 150th anniversary of the British Association, held at the University of York. Any help will be appreciated - a collecting friend from Worksop has asked for details of who organised the envelope, and who actually flew the balloon.
