Ok, our next stop on the mural tour is on NE 28th near Davis. This abstract design is signed "Seak Joker Daim" for the trio of artists who created it. The RACC's defunct Murals of Portland website [archive.org link] says it was painted back in 2003. That was during the time when City Hall was paranoid about allowing murals anywhere, for fear of having to allow billboard ads everywhere. So I'm not sure how this one came about in that climate. Joker is a Portland-based artist (interviews at Graffuturism & Futurism 2.0), while Daim and Seak are German and I gather are fairly prominent in the street art world over there. So maybe that's our answer: I could easily see 2003 Portland bending the usual strict rules a little if an artist was famous enough, for fear of getting a bad reputation in the art world.
