Sculpture in Medellin by Alonso Arias Vanegas (of whom I have not been able to find any information)

I used to stare at this sculpture with curiosity back in the 70's, when I was in kindergarten and my school bus drove by that street. A couple of years ago I had to make a point of walking by and taking a couple of pictures of it. This, however, is not the photo I took. I grabbed this one from http://medellinrevista.blogspot.com/
