In a nutshell, the name and recognizable identity including basic model designs and names, logos, fonts, headstock designs, name-brand 'heritage', etc. has been purchased and is being used- and, it seems, has been by more than one organization, or a series of them; apparently some were made in Japan, some in Korea, and... ? I don't believe there is any further direct linear connection between the original John D'Angelico guitars and these, and certainly even less than that of current Fender and Gibson and their origins. The D'Angelico marque has been "revived", not unlike Indian motorcycles.
Doesn't mean that they're bad or inferior guitars, though!
