A group of Spanish mothers have stripped off for a racy calendar to raise the funds needed to resume a school bus service that was scrapped by cash-strapped authorities in an austerity drive.

 The calendar, which shows the mothers in various states of undress posing along the bus route, has already sold thousands of copies and raised awareness of the cuts to the education system across Spain.

"I´ll do anything for my child and If I have to undress, because in Spain that´s what has to be done to get attention, then I´ll do it," said Maria Gilabert, one of the mothers with a child at the Evaristo Calatayud school in Montserrat in the eastern Valencia region.
