GREENSBORO, Pa. — Giving sultry looks and sexy smiles to the camera, 12 Pittsburgh-area women recently posed at Monongahela historical sites, baring it all — or almost all — to create a charity-driven calendar.

The catch?

The nearly nude ladies are all in their 70s and 80s, driven to adventure by a desire to raise money for a historical society in Monongahela, a small community 17 miles southeast of Pittsburgh that they call home.

Overcoming fears the priest would walk by during a photo shoot or embarrassing their children and grandchildren, the women — all well-known members of the tight-knit community — are now eagerly awaiting the calendar's debut next month. The money it generates will go to the Monongahela Area Historical Society.

"One of the advantages of being old is that you can do anything you want and get away with it," said 80-year-old Lois Phillips, who as Miss September was photographed in the back seat of a 1968 Mercury convertible.

The calendar was the brainchild of 80-year-old Lorys Crisafulli. She came up with the idea when she saw the movie Calendar Girls, a 2003 flick starring Helen Mirren in which a group of British women publish a nude calendar to raise money for cancer research.

"I thought, why don't we do that in Monongahela?" she told a Pittsburgh newspaper. "We need something to put us on the map, to get us going."

Crisafulli spent the next few weeks finding sponsors, a free photographer — Chris Grilli of Grilli's Studio in New Eagle — and an eager group of septuagenarians and octogenarians with enough spunk to show some flesh.

A former fifth grade teacher, Crisafulli is about to become better known as Miss January, who lounges in a black convertible covered in pearls, holding a champagne glass in one hand and dangling slinky sandals from the other.

Some of the other photos are more risque.

Miss April, Esther Cox, poses in a pasture, nothing but a pink umbrella covering her 75-year-old body. Miss December, Sondra Odelli Bordini, gives a sultry glance from behind a poinsettia centerpiece with two strategically placed red Christmas balls.

The 2008 calendars will be sold in local stores and on Monongahela's Web site, www.cityofmonongahela.com, for $10 a piece.

The historical society, a cash-strapped volunteer group, was surprised, but pleased to be the beneficiary of the project.

"The fact these lovely ladies did this, it's very touching and very much appreciated," the society's president, Susan Bowers, said.
