8 postcards set lot Japan paintings ethnic traditional dress unposted packet

This is a set of eight postcards showing various illustrations of Japanese people in traditional dress, and other views. They come with their original small packet, and may date from the 1960s ?

The cards are in fair condition, with minor wear to the corners and edges.  Unfortunately there is some marking on the backs - it is not clear whether this is fading or staining.  However, the fronts are fine.  The packet has some minor wear.
