Empty Billboards

Billboards are everywhere, at least in Puerto Rico. The sudden trend of empty billboards along the streets & avenues of Puerto Rico has gotten to the point where I couldn't avoid them any more and had to start collecting their images as they stand still in our pathways lifeless and seemingly forgotten. What is it about them that I feel so compelled to stop and take pictures? Whats the appeal? Maybe is the way that you can see through them as if they advertise just clouds and blue sky, or perhaps is just because it reminds me of change. One thing is for sure, among the many things we encounter and interact in our daily lives some of the more amazing feelings comes because of what it reminds us that is not there instead of the immediacy of the object. Whatever the reason might be I hope you like it.
