I live in Chicago (and in fact just got back from a walk in a park!). I will be outraged if I see one of these in my neighborhood. Sadly, if this isn't in fact a mistake, it won't be the first time in recent memory that city leadership has accommodated dubious private interests in public parks (see [1] for example).

EDIT: fix typo
