The income of British singer Amy Winehouse quadrupled following her death.
New documents, obtained by Britain's The Sun, reveal Winehouse's company Cherry Westfield posted profits of around STG1.1 million ($A2.05 million) for the 18 months to April, 2013.
The income is around four times as much as the STG257,353 recorded for the period of 12 months ending in November, 2011.
Winehouse died in July, 2011. Fans subsequently flocked to buy her recordings, pushing them up the UK charts.
An album of previously unreleased material, titled Lioness: Hidden Treasures, scored her a posthumous number one in December, 2011.
