what is this?

our pal matt went to greece and brought us back a gift. it's a tile plate that you hang on the wall. he reported to us that these were being sold at all the little stands in greece.

my questions are :

what is the story behind this?
is there no story behind it, but some joke in order to laugh at tourists?
is the monkey flushing?
that banana looks extremely phallic
