Banerjee's paintings on sale were titled 'Twenty-five Hours a Day'.
Banerjee was busy painting on the days of the Indo-Pak seminal match and India-Sri Lanka final match of World Cup.
Banerjee's brush with colours will finally come in handy for her party. The Trinamool Congress claimed its greatest weakness in its run up to the upcoming Assembly polls was its paucity of funds.
The Trinamool's election manifesto - with its high-resolution pictures and multi-coloured print on glossy paper suggest the party spent quite a fortune - something that goes against its claim of a fund crisis.
It seems Mamata Banerjee wants to leave no stone unturned to avoid all possible roadblocks to taking on the Left.
About 100 paintings by Banerjee are on display at an art gallery in Kolkata.
The three-day exhibition opened on April 4.
Banerjee had earlier handed over the paintings to Jago Bangla, the official mouthpiece of Trinamool Congress, in order to raise funds for elections.
The paintings were put up on sale to raise funds for the assembly elections. Thirty of her artworks fetched Rs 60 lakh.
The paintings had titles like 'Jangalmahal', 'The Rhythm of Life', 'The Dawn', 'Unseen Dream', 'Faded Beauty' and 'Wind in Blue'.
In 2007, Rs 12 lakh was raised in a similar way. The amount was distributed among families in Nandigram.
In 2010, Banerjee drew up a list of select 2,000 people in Bengal to whom she gifted a greeting card designed her, that carried her printed signature.
Party insiders say that Mamata always seeks feedback from close aides on her paintings.
But even if the effort proves insufficient to overcome the claimed fund-shortage, moves like these would clearly do a world of good to her image as a leader.
A TMC member said there were a number of requests from Australia and UK for the paintings.
Banerjee's passion for Rabindranath Tagore reflects in the paintings.
Senior Trinamool Congress leader Derek O'Brien said the response to the paintings was superb.
