Five characters on the picture on the right is a name of a historical person: 佐々木盛綱 (Sasaki Moritsuna)
Sasaki Moritsuna
So naturally I would assume the picture on the left would also be the name of another historical person, but it doesn't seem to be the case, and the meaning of the text isn't obvious to me. It kind of looks like a name, or names, but I'm getting no hits on Google.
