EXECUTIVES have swapped shirts and ties for their birthday suits to pose for a raunchy calendar.
The unlikely pin-ups were challenged to strip off for a good cause by female colleagues.
The calendars are being sold for £5 to raise money for children's charity the Jennifer Trust.
Sunderland's Regional Technical Centre got involved with the trust because of worker Michael Bath, 36, who lost his daughter, Jenny, to the muscle-wasting disease spinal muscular atrophy 11 years ago.
Michael and his wife, Anita, of Burnopfield, County Durham, went on to have two healthy children Peter, nine, and Rosie, seven, but have never forgotten their daughter, who died at five months.
In her memory, the couple are trying to raise money for research into the terminal disease.
Michael, a technology transfer executive, entered into the spirit, baring his chest and donning his rubber gloves as Mr January.
He said: "We had lots of willing volunteers to take part, all quite happy to appear in varying states of undress. We've sold 300 copies so far, but we want to sell at least 1,000 more."
