A photo that shows two walls on the side of an abandoned grocery store. The walls are usually covered with wheatpasted ads, but several artists have covered over these ads with cute collage art. There's a large cat collage on the left, and a dozen different posters and collage pieces on the right.

A closer look at a collage of a cat wearing a dress and shoes. The cat is surrounded by butterflies, with text nearby that says "The only monarchs we need"

New installation by "Art Not Ads" on Mission St. This collective reclaims spaces that have been covered by ads. #ArtNotAds #SFGraffiti #Graffiti #Collage

A wheatpasted poster on a wall that is covered with other posters and graffiti. It is a black and white poster showing Gort and Klaatu from The Day The Earth Stood film (a 1950s science fiction movie) and a spaceship. Red text on the poster says "Klaatu barada nikto, dammit!", which is a reference to a line in the film. The two characters look very retro science fiction, one is supposed to be a giant robot, the other is a humanoid in an unusual spacesuit.
