"The Lilac One" is No. 12 of the "Andy Series". The "Andy Series" is an ongoing and numbered Popart series, that covers day-to-day topics in a humerous way such as fashion, future, growing up, various views of life and much more. Every painting has a primary colour naming it (The Red One, The Pink One etc.). On all paintings indirectly a person called "Andy" is playing a role, but you never see him.
