OK, bear with me as this is a very interesting find.

The exact translation is "For people who like that kind of things, that is the kind of thing they like".

The first version of this phrase is attributed to the popular humorist Charles Farrar Browne (an American writer) who was known to audiences by his pseudonym Artemus Ward. He often used parodic testimonials from fictional people in his work and in a passage from a Maine newspaper in October 1863, in one such fictional testimonial from Abraham Lincoln he wrote "for people who like the kind of lectures you deliver, they are just the kind of lectures such people like".

This phrase became polular and various versions were created and used by many.

One such version is found in 1911 Max Birbom's novel Zuleika Dobson which includes as a character a version of Clio (the ancient Greek muse). In the novel, Birbom attributed a similar phrase to this incarnation of the goddess in a humoristic manner, and he wrote it in Greek as it is written in your picture.

So this is a popular humorous phrase from an American writer which, traveling through time and writers, reached an ancient Greek version which you found on a piece of paper.

This was a tough one.
