These three fiberglass cows on City Hall Plaza are part of Boston's Cow Parade this summer. The one in front looks like it's sporting van Gogh's "Starry Night" painting (for more, click here: en.wikipedia.org/wiki/The_Starry_Night). The one on the left carries the darkness of space and a fiery star on its midsection. The one on the right I call the "In Wheat Shall Be Your Profit" cow.
Last December I posted this shot -- www.flickr.com/photos/antydiluvian/79916877/ -- of one of the first of these cows to be displayed.
(Each cow has a nameplate on its base, as well as its artist's name. I was hurrying to North Station to catch my train and didn't have time to read them. Sorry.)
