Jammed under the wipers, then often ejected to the street, the windshield flier may soon be jettisoned from the ranks of legal forms of advertisement in the city of Pittsburgh.

Councilman Bruce Kraus today plans to introduce legislation that would ban windshield ads, which he said often submit visitors, residents and even schoolchildren to unwanted images and messages -- not to mention messy streets.

"I see it on the South Side every Saturday and Sunday morning, but I'm sure it's happening in the Strip District and Lawrenceville," he said. "By morning, it turns into litter."

His office yesterday showed fliers featuring barely clad women and advertising parties and events -- a tame sampling, compared to some of the fliers they have turned over to the Department of Public Works.

"They end up all over the street and in front of Phillips Elementary," Mr. Kraus said.

Several fliers advertised Privilege Ultralounge in the Strip District. Owners of that club could not be reached for comment.

Not offensive was a flier advertising belly dancing at Your Inner Vagabond, a Lawrenceville coffeehouse. Co-owner A.J. Schaffer said the artists -- rather than her lounge -- do the leafletting, which she discourages.

"I am very much against litter," she said, adding that a law against windshield leaflets would help her discourage artists performing there from doing it.

The legislation would impose a $15 fine, plus court costs, for a first violation, and $500 for subsequent violations -- standard for small sign violations in the code.

Mr. Kraus said the ban should be enforceable, noting that the Department of Public Works cites businesses that break rules against posting ads on public surfaces like street poles.

His legislation would explicitly allow the posting of lost pet fliers on public surfaces. That issue came to a head last month when a public works employee threatened Nicole and Chris Currivan of Shadyside, owners of lost dog Mochi, with fines for their signs.

Mochi may have left the city limits, Ms. Currivan wrote in an e-mail, after a weekend report of a sighting in Penn Hills.
