Here are the other two things I found on my night walk Tuesday. I may have to go back in the daytime to get decent pictures of both stickers but for now these will do.
Another appearance of the sausage. I like this one although it looks as if somebody tried to scrape it off with a metal brush or something. This art also looks a lot like the pill previously posted here.
Another fish sticker as well. Both of these stickers were near the intersection of 39th and Lincoln.
