Question: How much money for an autographed Campbell soup?
About the article "Andy Warhol", section "1960s".

Candidate passages:
 "Our lives are mired in detritus.
Objects own us; they keep us from our creativity."
"Why would anyone pay $3,000 for a hunting knife?
They say, because my name is on it.
I'm carrying an awfully big rep.
If I were a gunfighter, I'd be hiding in a cave somewhere.
But I wouldn't spend that much money for a knife if it were autographed by Jesus Christ himself!"
"What's the point of a new knife in a museum or a cabinet?
That's for history to decide, not the knifemaker."
"When a man picks up a knife, there's an old memory from the collective unconscious that surfaces.
A knife is an atavistic experience.
It was man's first tool and weapon.
Man was chipping flint into cutting edges before he invented the wheel.
No matter how sophisticated we become, a knife takes us back to the cave."
In 1976, Thornbladh returned to the University of Michigan as a graduate assistant on Bo Schembechler's coaching staff.
In 1976, Thornbladh accompanied the team to the Rose Bowl and was the subject of an Associated Press story about expensive soup.
Thornbladh was sent by Schembechler to get 15 tuna fish sandwiches and 15 cups of soup for the coaching staff.
Thornbladh placed the order at a nearby restaurant and came back later to pick it up.
The bill came to $50.56, and Thornbladh did not have enough money.
In order to avoid losing the entire sale, the restaurant agreed to sell him the 15 sandwiches without soup for $28.
After hearing the story, Schembechler sent him back to the restaurant the next day to buy a single order of soup, wanting to find out how "$2 soup-to-go" tastes.
In 1980, Thornbladh was promoted to assistant coach at Michigan, a position that he held until 1986.

Soups made with cream and mushrooms are much older than the canned variety.
Ancient Italian (Salsa colla) and French (Béchamel) cream sauces, and soups based on them have been made for many hundreds of years.
In America, the Campbell Soup Company began producing its well known "Cream of Mushroom Soup" in 1934, the same year that it introduced "Chicken with Noodles". 
David Wilson "Dave" Campbell (born January 14, 1942 in Manistee, Michigan) is a former American baseball player and current sportscaster.
His nickname is "Soup," an apparent reference to the brand name Campbell's Soup.
