According to her parents, Marla Olmstead began painting just before her second birthday in early 2002 when her father, Mark, gave her paint to divert her from distracting him from his own painting. Mark painted for a very brief period after his father died, and makes no claims of being an artist of any variety. Eventually, her work was on display at a local coffee shop. Soon after a customer bought one of the paintings for $253, a local gallery owner was shown one of her works and eventually organized a show at his gallery. From that point forward, Olmstead's paintings began to sell frequently
The popularity of her work took off after her first gallery showing, with many of the paintings selling for tens of thousands of US dollars.
To many art critics, what is most impressive about her is the ability to paint in layers and to fill the canvas, instead of painting in one layer and leaving most of the canvas blank, like other four-year olds. The skill demonstrated in the paintings has prompted critics and media to draw comparisons to abstract artists Wassily Kandinsky and Jackson Pollock. Marla has attracted media attention from The New York Times, Time magazine, CBS News, and BBC News.
