Well , I'd give an only-seen-a-picture-of-it opinion that the style of this art is sorta very much like that done by tatoo artists ... 1930's thru 1950's , to my eye .
Looks more 'street-vendor' style (perhaps near a mil base) than anything else I might suggest .
Sometimes , in post-war Japan (and in wartime Korea) , 'native' peoples would use english 'spelling' , often near the phonetic of an actual name , so that servicemen/customers would able to identify & remember a name ( such as -for example only- Lin Hue) .
