Vtg Duluth Monarch Brand Backpack #4 Paul Bunyan Huge Canoeing Portage Huge. I believe this would be from the 1940s, but could be a little earlier or little later. Backpack is very, very large. Canvas and leather, the canvas has some holes that could be patched. The leather seems decent for the age, but not sure it could still hold up for use. Brass rivets could use some polish as they have a little corrosion from the humidity. Been kept in an attic for many years, I gave this a rinse off, but it still could be aired out for a bit as it is a tiny bit musty still. Always happy to answer any questions if I can.We will combine shipping, especially on small items it cost the same to send multiples as it does to ship one.
