We slinked about Betterwall more than a year ago, so it was about time to revisit their current selection of Los Angeles limited-edition museum street banners. The LACMA Eames exhibition and Bill Viola banners are our favourites of the current Los Angeles selection, but we're admittedly more gaga over the Dada banner from the NY Museum of Modern Art. And how machine modern marvelous is this Swedish Design Ball-Bearing banner from MOMA? In this case, NYC trumps LA. But where are the LACMA Magritte banners? These advertisements-as-art also support the museums, as a percentage of all sales goes right back to the art institution whose banner you chose. Starting from $359 and printed onto 2-ply vinyl.
