1960s/70s Leather Shoulder Bag with Puzzle Lock

1960s/70s leather shoulder bag with leather strap and brass ring hardware. Flap folds over and locks with a door knocker ring "key" that twists through a brass hardware "lock". Reminds me of vintage Coach in its construction and lines. 

12" x 11" (23" total with strap) 

Condition: Very good. Minor scuffing at corners
