The 6th annual Mister Freeze exhibition is just wrapping up this weekend, and this was our second year touring the astonishing works of graffiti. The exhibition was held from September 29 to October 7, and included the works of 30 local, national and international artists on display in the former Latécoère airplane factory. The exhibition covers a total of 11,000 square meters. Basically, the artists are given free rein to do as they wish with their sections of the massive concrete walls. The results are sometimes moving and sometimes just mind-blowing.
