I've featured plenty of Morning Musume cards on this blog. But when it comes to idol music cards in Japan, really there's only Morning Musume and AKB48 (with their sister spin-off groups). AKB48 is still really popular, so it's only the senior group that I find "abandoned" in the clearance bins at my local haunts.
This issue has lavender-colored envelopes and the top spine is green, containing the English text "new morning garls nama photo".
Here are the cards I pulled from my taba:
These were produced by Amada in 2002, a company which made a bunch of Morning Musume's cards. There are 85 cards in the full set: 72 "normal" cards and 13 special ones.
