Nearby another sticker declares a green fire hydrant an art object worth $10.
The dots are all around downtown Appleton - on cigarette-butt containers, trash cans and parking meters. They all have "Art Object" typed on them, with prices ranging from one cent to $10,000.
Friday marks the city's monthly "Art on the Town," a celebration of art in the community. But coordinators of the program say the stickers aren't theirs.
"It was definitely not us," said Mary Ann Wepfer, the marketing director of Appleton Downtown Inc. "But when you find out who did it, let us know. We're always looking for ideas."
Linda Muldoon, a local artist and gallery owner, marveled at how the stickers turn ordinary objects into something special.
"It's nice that someone, by placing a sticker on an object, can make it a piece of art," she said.
A dispatcher with the Appleton Police Department said Friday morning she wasn't aware of any complaints about the stickers.
So far no one has claimed responsibility for the dots, but Muldoon speculated that nearby Lawrence University was behind the scheme.
Rob Neilson, a Lawrence assistant professor of art, wouldn't say whether his department had anything to do with the stickers. But he did say the dots were serving a fundamental role in art
- to instigate thoughtful discussion of profound and provocative ideas.
