Last weekend, Mr. Brainwash invited the Seventh Letter Crew over in order to kick off his largest Los Angeles exhibition to date. Beginning on October 9th, the building that sits near the La Brea and Santa Monica will open it’s doors to artists around the globe and will offer over 80,000 square feet of blank walls and concrete. The long talked about project had been circling around for months without any sense of progress but clearly things are now moving forward.

The staircase that sits inside the 5 story building was painted entirely by the graffiti crew and by all looks, this section of the building may be one of the upcoming show’s main attraction. It will be interesting to see what the building will look like after the open artist installation ends on October 12th.

Check out the pictures after the jump to get a sneak peek of the weekend’s secretive event.
