His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections.

Question: In what year was baseball first played in the stadium for which  Rostenkowski secured a $150 million bond authority? Passage:In his book , author Charles Wheelan wrote "We Chicagoans can drive around the city and literally point to things that Rosty built." Although Rostenkowski never "literally" built anything with his own money or labor, he delivered federal funds for Chicago and the State of Illinois. Some of his notable projects include: securing $32 million for the Blue Line of the Chicago Transit Authority which expanded travel from the Chicago Loop to O'Hare International Airport, $450 million to repave and expand the Kennedy Expressway, $25 million to fix the dangerous S Curve on Lake Shore Drive $4 billion for the Deep Tunnel Project, which was designed to keep raw sewage from entering the Chicago River and Lake Michigan, while also protecting over half a million suburban and city home owners threatened by flooded basements. He followed that with $42.4 million for reservoirs in McCook and Thornton Townships and by O'Hare airport, $16.8 million for downtown's State Street Mall renovation, $3.5 million for the construction of the Cook County Boot Camp, a military-style alternative for first-time youthful offenders. When the Chicago White Sox baseball team was considering moving to Florida, Rostenkowski secured a $150 million bond authority for the construction of US Cellular Field. Once nearly abandoned and left in disrepair, he ensured $75 million in tax-free bonds for the remodeling of Navy Pier, which today has become Chicago's preeminent tourist attraction. To ease erosion that threatened Lake Shore Drive and several harbors and museums along the Chicago lake front, Rostenkowski secured $2.2 million for the Chicago Shoreline Protection Project, and laid the foundation for a coordinated partnership among the Army Corps of Engineers, the federal government and the City of Chicago. He also was responsible for securing funding for the upkeep of Chicago area bridges including the Chicago Skyway, the Division, Cermak, and Roosevelt street bridges.
