This is a very small museum that I was hoping would give me a better appreciation of Graffiti, but it didn't. I read much of the presented content - found it mildly interesting but many of the "artist" stories were similar. Seemed very superficial in scope.
I wanted to understand the difference between tagging which I consider vandalism and graffiti, which I thought was more of an artform. There seems to be some elements of art/design but I left still thinking it's more about the tagger's ego and his attempt to cover the world with his multiple names or gang names. Not art at all. I was also disappointed that the museum made no attempt to explain the negative effects of graffiti. ie., they can make you very uncomfortable about your environment and the destruction/degrading on historical building. While the bathrooms were good examples of graffiti on steroids, had they been any other place, I would be very leery about entering and using them.
Wynwood runs the risk of becoming obsolete because the beautiful street art is damaged by tagging and graffiti along with every inch of surface; sidewalks, telephone poles, etc., now looks rundown and out of control. Its graffiti and tagging at its worst, especially if you had seen the area 5-8 years ago, when it was truly innovative.
I read nearly everything. It took me about 1/2 hour - indeed a tiny museum not really worth the expense to enter. However the gift shop is free to enter and amusing.
