HARRISBURG, Pa. (AP) _ A sculptor spent three 14-hour days in a cooler to create a startling likeness of Benjamin Franklin, knowing that it would end up in peoples' stomachs just a few weeks after it was done.

Raymond Mackintosh of Toronto used about 600 pounds of Pennsylvania butter to build the life-size sculpture of Franklin for a special display at the 75th Pennsylvania Farm Show, running this week through Friday.

The sculpture, displayed in a refrigerated booth, regularly draws a crowd.

It portrays one of the state's most colorful historical figures standing erect, intently reading a piece of paper. He holds a pair of glasses in one hand near his chin.

It is detailed down to the knee wrinkles in his hosiery, the ruffles at the bottom of his sleeves, the frayed edges of the paper and the buckles on his shoes.

''I wouldn't have the patience for that,'' said one spectator, Joanne Herr of Columbia. ''He did a good job.''

''It's an artistic way of promoting a product,'' said her husband, Elmer.

Officials from the four dairy organizations that sponsored the sculpture estimated its worth at about $5,000.

After the show ends Friday, the statue will be taken down and the butter donated to a local soup kitchen.

Mackintosh, who also has created special effects and masks for such films as ''Jacob's Ladder,'' said he took a break from his current movie, ''Body Parts,'' to shape Franklin in butter.

''Actually, it's an interesting material to work with,'' he said in an interview from the ''Body Parts'' set in Canada.

''I had to work in cooler temperatures and it was cold. I was fighting hypothermia. Fatigue sets in quicker,'' he said. ''You have to stay warm while concentrating on what you're doing.

''Butter is tricky, but then you get used to it. I like it, it's very responsive.''

He used wooden and wire tools he made himself to craft the intricate details. The sculpture hides a steel frame that supports its weight.

''I know it's a temporary thing, but if people enjoy it, then it's fine. It lives on in their memory. A lot of people base past experiences on seeing a butter sculpture. It sticks with them,'' he said.
