Profits from sale of the calendar will go to the Bosom Pals breast cancer appeal.
The calendar is said to be unusual among bare-all calendars in featuring both men and women.
Among those taking part are: Marc Miller, managing director of local amusement park Adventure Island; Jimmy Howard and John Harland, respectively general manager and marketing manager of Maxim’s Casino in Southend; Emma Wynne-Morgan, publisher of local glossy magazine Leigh & Thorpe Bay Oracle; and the Southend Airport firemen.
The calendar is the brainchild of local photographer Jo Curtis, who took the snaps. She said: “We wanted to do something fun to raise money for a fantastic charity and promote some great local businesses at the same time.”
