In 1995, had a song written about her by the band Fossil titled Josephine Baker. In 2003, another musical went on stage, in Belgium, called Simenon et Josephine. It was a musical comedy related to the Maigret year of 2003 in Belgium.
There is no salary cap in MLB. There is however, a luxury tax system which makes it more expensive for a team to carry a high payroll. How it works is that there is a threshold ($189M in 2015); if a team's payroll is above that limit, a tax of 17.5% of the amount they're over by is paid to the league as a fine.
Because the NFL is a megalithic corporation that is somehow still growing at a confounding rate, the salary cap has taken some of its biggest leaps in recent years. The 2015 cap is more than $10 million richer than the $133 million salary cap in 2014, which jumped up another $10 million from the $123 million salary cap in 2013. That means the NFL has more and more money to spend on players themselves, making some, like Chicago's Jay Cutler, very happy.
