Ryan Barr of Whipping Post Leather makes these gorgeous guitar case bag backpacks.
"I always wanted to create a bag for my guitar that matched its character," he writes. "Something that could age with time and maintain its classic appeal like any well made instrument. The more it got used and abused the better it became. Kind of like my guitar."
