This bag measures roughly 6 by 12 by 18 inches. It is huge and very thick and heavy. It is an authentic mail carrier's post bag of the post office here in France. It has a faint eagle logo in black on the front of it, and 'les postes.' It's made of thick leather. Condition is great for its age. Rare. Wear-wise, I would say this is perfect; if it were any less worn, it would be impossibly stiff. It took it a good long time to get supple.
