...I like that you share your thoughts +Bryan Lowery ...(:
...the thing with this kind of art is that each artist is unique ...some are practicing ...for others, the image is the signature, and it will crop up in various places ...large works are tagged ...where they are, I make sure that I include it in the image, or mention the artist
...some go so far as to include an instagram or web addy, so anonymity isn't necessarily the driving force for lack of identity as street art becomes an acceptable form of social expression, in some areas
...speed is of the essence ...I put a lot down to that!
