Monarch Brand vintage Duluth Pack canoe pack, green drab canvas & leather backpack

Vintage cotton canvas and leather pack, Monarch Brand. I believe this is called a Duluth 'canoe pack' - made and marked Monarch, as shown, numbered 51. Style is called Duluth Pack, it's not a Duluth Trading Company bag. Pack measures about 18" x 19".

It's well made, sturdy, heavy fabric and thick leather in good condition. Used, spotted from water and light soil. But fabric and leather are supple and in good condition, no dry rot or brittleness, no fading.
