In 1973, after five years of negotiations, the Paris Peace Accords were finally signed to bring an end to the Vietnam War. The four signers represented the United States, the Democratic Republic of Vietnam (otherwise known as North Vietnam), the Provisional Revolutionary Government of Vietnam (otherwise known as Viet Cong), and the Republic of Vietnam (otherwise known as South Vietnam). The agreement contained a cease fire and a promise to remove all foreign troops from the country. 

Yellow, white, green and red text on black background with photographs of Mike Tyson and Evander Holyfield. 

Heavyweight champion boxers Mike Tyson and Evander Holyfield were scheduled to fight on November 8, 1991 at Caesar's Palace in Las Vegas. Tyson had lost his title to Buster Douglas in 1990, and Holyfield defeated Douglas later that year to become the reigning champion. After Holyfield also beat former and future champion George Foreman, a deal was signed for Holyfield to defend his crown against Tyson in Las Vegas. The projected gross earnings for the fight were over $100 million. TVKO was the event production leg of HBO that was slated to show the 1991 fight on pay-per-view television. Tyson was indicted on rape charges in September of 1991, but the fight was not canceled until Tyson claimed he had suffered an injury in training. Tyson was later convicted and imprisoned for three years, but the two finally had their first match in 1996 following Tyson's release, which ended in victory for Holyfield.

The 32^nd Republican National Convention was held in July, 1980 at the Joe Louis Arena in Detroit Michigan.  This was the third attempt for Ronald Reagan at a nomination (1972, 1976).  Reagan arrived at the convention with 400 out of 478 delegates in his favor.  Although rumors floated around about a Reagan-Ford ticket, discussions between the two broke down and Reagan chose George W. Bush as his running mate. 

The pairs’ slogan was “Let’s Make American Great Again.”  Reagan and Bush overwhelmingly defeated incumbent Jimmy Carter for the Presidential Election.

Busch Gardens Tampa is an amusement park located on 335 acres in Tampa, Florida. It opened on March 31, 1959 and was originally tagged as "The Dark Continent" due to its African theme. The park was originally developed as a marketing tool for Anheuser-Busch and housed some of the company's recognizable Clydesdale horses. A subsidiary of Anheuser-Busch, SeaWorld Entertainment, operates the park in Tampa and a second park located in Williamsburg, Virginia. Busch Gardens Tampa now features thousands of animals, a replica steam train, bird gardens, rope bridges, thrill rides and roller coasters. The park was the first to offer animals in a free-ranging environment with the opening of its Serengeti Plain animal habitat in 1965, which now covers 65 acres.

On July 18, 1985, three Chicago Tribune unions walked out on bargaining sessions for new contracts.  The unions that went on strike totaled over 700 workers and were the Chicago Typographical Union No. 16, Chicago Web Pressmen’s Union Local 7 and Chicago Mailers Union Local 2. 

A year later 68 bargaining sessions had been attempted, and the newspaper had replaced a majority of the strikers with new employees. Teamster Union drivers crossed picket lines, honoring the no-strike clause in their contract.  Seven other unions also crossed picket lines.  The union leaders hoped to succeed in garnering support for the strike with 100,000 newspaper subscription cancellations.  However, there was a lack of public interest in the strike, and the newspaper reported around 5,200 subscription cancellations were attributed to the walkout.
