It's an absolute rarity, but examples do exist, like this. A BANNER Gibson J-50. This 1942 J-50 is one of the first J-50s made and utilized a beautiful set of Adirondack spruce that would become a rarity during the height of WWII rationing (making the sun bursting of J-45s more preferable to mitigate quality concerns). Early "Banner" Gibsons, like this one, still have trussrods (which also became rationed). Apart from the obvious mystique about how rare it is to find a natural topped wartime slope shoulder model like this, it's worth reiterating that J45s and J50s are a songwriters best friend. It's one of the most suggested "if you can only have one guitar" models. The perfect Gibson acoustic hunt also requires consideration for neck shape, and this one is perfect. These earlier "Banners" have chunky, but not fully baseball bat necks like later ones. This example has had typical maintenance over the years: neck reset, bridge reglue, refret, replacement maple bridge plate, and glued minor back cracks. Much of the music we have come to love was played on these guitars; it's very reminiscent of Bob Dylan's infamous script logo J-50.
Comes with modern hardshell case.
