We are embarrassed to admit we do not know the correct term(s) to describe this card accurately.  Bear with us.  It has a message on the reverse and was likely mailed in an envelope:  no sign of stamp or postmark.  The card itself is on extremely heavy stock that almost looks embroidered, or like tree bark.  (We said we didn’t know.)  Try to imagine a card that almost looks like needlepoint, but not as thick.  The maker is “Numai” and there is some Japanese printed on the front but search engines were no help.  Grade: 4
