The monster whose upper body is a horse and the lower body is a fish should be a monster in Greek mythology, called "bijuu, a horsehead fish". This is Poseidon's mount, also known as the "seahorse", and its image is also on the badge of the Middle Ages. In addition, this sign appears on the freezer of the container, which is probably the trademark of CRONOS, a container leasing company.
