Saw this on the side of a building and was captivated by her. This was created by Michael Biondo, a local Buffalo artist. Here's his website, biondoart.com.
I really like this image, especially the fact that you have included the context so it gives some idea of the dimensions and location. No wonder you were captivated.
I cannot begin to imagine how complicated it must be to paint something that size I haven’t gone to his website yet, but I wonder if he did it in pieces and then assembled it or hung that canvas up there and then painted it
