According to the map provided by MOCA, there are 14 Invader pieces that went up surround the Art In The Streets Exhibit. These are the few I captured on my first visit. You can bet I'll be hunting the rest down shortly.
In lieu of doing his installation in one specific section of the gallery, Invader opted to utilize the entire building itself, inside and out, in order to engage with the visitor and the space. Half the fun of checking out his work is trying to find each piece.
Incidentally, Invader was the first artist arrested in connection with Art In The Streets.
