I've ridden this ship when I was still a kid...
Sadly, there are no photos (yet) of the MV Philippine Princess online.
So, here's my concept of what she might've looked like =)
Thank you for everybody who helped me make this second concept as nearly accurate as possible =)
Original "Naha Maru" photo was from Funekichi Murase's website
