More pics of the japanese blue and white bowls

The only thing I could figure out is that they aren't really old because of the English marked on the bottom. But no idea of the brand or if it's just a souvenir from maybe a little street vendor. My mom also has some of the old man's postcards and one was from 1951 so Idk if that was when he went or if it was a different trip. There are 4 so it's part of a set. Thanks again for the help, I'm definitely lost on this subject lol.
