Okay, this card is over franked but I still consider it as very commercial. Possible that the sender was not aware of the correct required postage thus with the note "Am rushing this letter that is why I put plenty of clipper stamps...."

Except for philatelic notices the commercial use of the Rice Planter card is not easy. I personally have help prepare numerous Japanese Occupation exhibits and this card is sparingly represented in the collections. The other matter I would like to call your attention to is the difficulty of finding registered postal cards and this is true for all countries that issue them. In reality, there is no need to register them.
