The History of Chicago Sidewalk Nameplates (Stamps and Plaques).

Sidewalk stamps can be found on the streets of small and large American cities. These ubiquitous inscriptions are the proud commemorations of a job well done and a practical and long-term form of advertising. They are also explicitly required by law.

CITY OF CHICAGO RULES

RULES REGARDING CONSTRUCTION IN THE PUBLIC WAY UNDER

2‐102‐030(L); 2‐102‐040; 10‐20‐210

LAST UPDATED JANUARY 2014

Before the top or finishing of concrete walks has set, the contractor or person building the walk shall place in such walk in front of each lot or parcel of property a stamp or plate giving the name and address of the contractor or person building the walk and the year in which the work was done. The top of said plate or stamp, which must not cover more than 54 square inches of surface, shall be flush and even with the top of the finished walk, and must be of a permanent character plainly stamped or firmly bedded in the concrete in such a manner that it cannot become loose or be easily removed or defaced. Wherever one contractor or person has laid walks in front of three or more adjoining lots or parcels of property in one continuous stretch, one of the above named stamps placed in the walk at each end of said stretch of walk will be sufficient. (Prior code § 33-38; Amend Coun. J. 1-14-97, p. 37762, § 44)

The city code was adopted to hold the contractor responsible for their work should anything be defective in the concrete sidewalk they laid.

There are two different types of Nameplates, stamps, and plaques, and they serve two purposes — identification and advertisement.

The most common type of sidewalk marker is stamped into newly poured concrete. It becomes an indelible feature of the sidewalk, sharing the same space as children’s footprints and lovers’ inscriptions.

Stamps most often bear the name of the construction firm that laid the sidewalk, and the year the work was done. Additional information can include the company’s location and telephone number. Sometimes a stamp will carry broader information, such as the name of a subdivision and its developer.

The less common form is a precast brass plaque set into wet concrete. These are not “stamps” as such, although they are used similarly. 

Stamps and plaques are “permanent” in different ways. Stamps are part of the sidewalk and rarely filled in or removed. However, they are easily and often lost when a portion of the sidewalk is reconstructed. There are rare examples where an old stamp is integrated into a new sidewalk, but this is an exceptional occurrence. 

Brass plaques can be more easily removed from a sidewalk, although they are also most often removed when the sidewalk is reconstructed. They do have a better chance of surviving as individual artifacts.

Racists Miss the Point of this Billboard in Justice, Illinois; September of 1991.

A controversial billboard on the Tri-State Tollway designed to focus attention on racism on golf courses has been vandalized and will come down only six days after it was put up.

After the billboard was spray-painted with racist messages and a swastika over the weekend, artist Mark Heckman and the billboard company decided the time had come to take it down, even though it was supposed to stay a month.

"The billboard has served its purpose, and I don't want anyone getting hurt," said Heckman, who has parlayed the controversy into morning national talk show appearances for later this week. "So I don't have a problem with the sign being removed."

Tom Carroll, an official of Gannett Outdoor Chicago, the billboard company, said the sign, which advertises the fictitious Afro Country Club, "Where only the ball is white," is slated to come down barring high winds or rain. The billboard, located just north of 83rd Street in south suburban Justice, is visible to northbound tollway traffic.

Heckman, 28, of Grand Rapids, Mich., said he has produced two dozen political billboards in recent years, but this one sparked the strongest reaction by far. "I want to stimulate people with my work, but not to violence." he said.

Since the billboard was put up last Thursday, owners of the public warehouse near the sign, as well as Heckman, have received a steady stream of harassing and threatening telephone calls. Many of the complaints to the billboard company were callers who believed that the country club actually existed, Carroll said.

The vandalism apparently occurred late Saturday night or early Sunday, with the culprits perhaps providing their own ladder to climb the eight feet up to the walkway ladder that is used by workmen to mount the billboard signs, said Justice Police Chief Paul Washich.
In addition to the swastika and the letters KKK, the billboard also was spray-painted with the initials J and M.

By early Monday, work crews from Gannett Outdoor had removed the graffiti and repainted part of the sign.

"It's difficult for me to believe that this could still happen, but that was the whole point of the billboard," Heckman said. "I hope it makes some people think about racism."

Despite the complaints, Heckman and Carroll said they have received many calls from people praising the billboard. Heckman said the work was paid for by an anonymous benefactor in Michigan and placed on the Tri-State, also known as Interstate Highway 294, because a location in downtown Chicago was too expensive.

The tollway billboard cost $3,500 a month. Heckman will receive a rebate for the unused time.
Among Heckma's better known billboards was an AIDS awareness sign displayed in Chicago in 1989. That work featured 2,001 condoms dipped in paint and thrown against a canvas.

Carroll said a "generic" and noncontroversial billboard would go up in place of Heckman's.
