Back in 2017 I realised that a large proportion of my time was spent on the A14 travelling behind a container lorry. I started to take in interest in what they had attached to them, and then looked at the piles of containers at Felixstowe docks and thought how beautiful they were. I studied the various types of container and how they were made. The image was made up of images of actual containers, all the same size, copying the logos of the companies and their actual registrations. I became more interested in the tiny differences in them rather than the containers themselves. I loved the way the sea leaves its mark on them. Then a friend encouraged me to enter it into the Royal Academy Summer Exhibition in 2018. It got through the first sift but failed the second. A friend collected it for me, but loved the original so much he gave me the asking price, but allowed me to make a limited edition of 30 prints from it. 25 of those have gone to new homes, two of them to Felixstowe, of which one hangs in a container handling company’s board room.
