I think the formal aspects of the composition are what prompted me to make this photograph. That said, I can't help but wonder about the origin of that corner condition. I think it is very cool. It seems like a practical solution to the problem of an odd angle bend in a brick wall, although a cynic might say it was just a cost cutting measure. I've heard it referred to as a pigeonhole corner, a name I really like. I wonder, was the architect viewed as a creative genius or as a schlub who was too lazy to cut bricks?
