This is the first painting of the series, featuring my friend Frank and my partner Susan. I needed to practise on some people who wouldn’t mind too much if the whole idea turned out to be a disaster. The style is looser than in most of the later paintings but I felt encouraged that the project was going to work and would develop with each new set of passengers. I also discovered a surprising enjoyment in painting shoes and bags. You have to agree, such important items in all our lives deserve their own five minutes of fame.
