Instagram user Ian Kelleigh (aka ikelleigh) says he's "living in San Francisco taking photos of things I see day to day." This apparently includes this classic old bit of advertising, which urges Tenderloin passers-by the "Fresh Up with 7up." Well, that's certainly better than some of the things you could "fresh up" with down there.
Photo submissions for Photo du Jour, Morning Links and Day Around the Bay are gladly accepted right this way in the SFist Flickr Pool, or tag them on Instagram as #sfist. That's what ikelleigh did, and look at him now!
