FYI, some of the photographed sidewalk ads are clickable and take you to the merchants website.
Location of one of them:
Pan left until you see a rombus shaped roof with square patches of soil and grass on it. Zoom in closer and take look on the right for a standing sidewalk ad.
I think so as well. The ads are too clear in comparison to surrounding area. One other ad I found stuck out a little bit more than the one I posted earlier.
