Help Me Identify This Brick / Bracket I'm trying to recreate the building in the picture (Berghain by Matteo Plateroti), but I'm having trouble finding what bricks, tiles, or brackets were used at the bottom layer with white stripes. 

I assume those are 1x2 tiles at the front but what are they attached to? 

Close-up (cut from a larger resolution image):
Picture little blurry, but this is what I see...  The builder attached the tiles to Part Number Forty-Seventy. 

Part #4864a, the (black) window piece is really trans-black in color, but the way it's used here, with it being reversed and all, obstructs the proper identity of the white 1x1 bricks, causing some viewing tricks on the eyes...
