These later exhibitions seem reminiscent of "CowParade" (established first as Zürich's "Land in Sicht" in 1998), which was ultimately developed into an exhibit not specific to one city, but appears to have inspired at least some similar city-specific exhibits including the Seattle Pigs (three years after the first "cow parade" debut, and entitled "Pigs on Parade" in the same fashion as a 1999 Chicago "Cows on Parade" exhibit). There's much more related information at the CowParade Wikipedia entry[1], with a long list of similar exhibits. [1] https://en.wikipedia.org/wiki/CowParade https://en.wikipedia.org/wiki/CowParade
