Every year, Morlen Sinoway opens the loading dock outside of his Fulton Market gallery to local artists and designers as a temporary exhibition space, coincident with and in response to the annual NeoCon trade show at the Merchandise Mart in Chicago. Now in its 5th year, the Guerrilla Truck Show has become quite the institution, with over 25 trucks exhibiting, and for many visitors to NeoCon, a must-see item on their list of things to do in Chicago.

We stopped there last night on our way out, and despite the pouring rain, the scene was vibrant as designers, artists and spectators hopped from truck to truck. Exhibitors included new designers, up-and-comers and local retailers like Materious, Craighton Berman, Noel Ashby, Designlabworkshop, Koomalsingh Design, Steven Teichelman and Angela Finney-Hoffman of Post27.
