And an interesting basket.
Pack frames are nearly universal historically as most cultures encounter the drudgery of carrying heavy loads over long distances. I am always searching for historic images to delve into to look for inspiration. Here is a nifty pack frame from the early 20th century of a charcoal maker from Japan. The frame looks like simple through-tenons in a rectangle. The pack basket appears to be fairly simple twined straw and I think the shoulder straps are woven fiber. He is also sporting some nifty looking waraji sandals.
