A recent cover painting for the New Yorker by Jorge Colombo boosted sales of the Brushes iPhone application to 2700 in a day.
On Monday, Mr. Sprang said the application had its highest selling day since it was first released into Apple’s App Store in August, with 2,700 copies at $4.99 apiece flying off the virtual shelves.
“That’s even bigger than when Apple featured the application on iTunes,” said Mr. Sprang, who estimated that on average the application sells roughly 60 to70 copies each day.
