`Tondo? is a Renaissance term for a circular work of art. In referring to an art historical term in the title, perhaps Warhol is beginning to contemplate his move beyond the commercial art stage to fine art. Typical of his work of the 1950s he has combined his blotted-line technique with vibrant colours. These were possibly added at one of his colouring parties, hosted at the fashionable Serendipity 3 cafe after its opening in 1954. He would encourage his friends ? some of whom would have helped him create the original illustrations - to colour the works with an inventiveness that adds to their whimsical nature. This process looks forward to the production methods of Warhol?s legendary studio, the Factory, in the 1960s.
