I have recently purchased a pair of Levi's from a vintage shop, and haven't seen a pair like them before. They have a big red Levi's label on the back, leather not paper, as well as red buttons in the fly. The top button has an "r" on it. They also have some quite unusual, but nice, stitching. I'd love to know if they are real Levi's and from what year (ish), and if they are rare/valuable? I don't know THAT much about Levi's so thought someone out there might be able to tell me about these!
