No logo. It's a sticker, and there are similar ones on the seat tube. It's clearly been refinished, but not well, as the paint is flaking all over the place. It's such a pretty frame that I wonder whether I might not refurb it before I sell it. I've stripped it down - or rather my 9 year old son did, (so proud!), and I reckon the frame will serve someone who wants a fixed gear well. I just don't know whether to repaint it first. Probably not worth it.
