Do the notations ⅃⅃⅃ ___ LLL mean anything? There are some notations above the characters:

⅃⅃⅃ ___ LLL
大      人    国

Do these notations mean anything?
I found a more clear picture. I think they are not letters or characters. They are only decoration for the "大人国". The reason is the angle of view of your picture.You can see your picture carefully again.
