In this digital age, the concept of 'photographs' has become largely ubiquitous and a part of everyone's life. We all have camera's in our pocket all the time, everyday. Storing these images has become the stuff of giant cloud storage systems that many of us can't even locate.
With graffiti, the storage of these photos was mostly relegated to physical books, or photo albums. These photos were considered as almost trading cards, as many of the graffiti pieces captured no longer existed. That physical photo was the only record of it.
Thus, these albums act as a physical record of countless pieces or art. Below are pages from one of mine. Late 80's, early 90's era.
