Uploader comment: I took this picture in the abandoned section of a local school on my Holga camera. I know Holgas are famous for their unusual images, but I've taken literally hundreds of pictures with this camer and have never seen anything like this. I also took several in the same place right after this and they all came out completly normally. I thought it could've been an error in printing, but the image is very clearly on the negative. I have no idea what this could be.
