After speaking with the director of the Princess Diana Museum, she confirmed it’s possible, albeit quite unlikely, that Diana may have signed a card if someone brought one over from Japan to the UK before her passing (her last trip to Japan was February 1995).
The possibility is important, because I had feared there may have been restrictions on what she could publicly sign in 1996-1997. But since that is not the case, it’s possible a signed card exists.
I therefore have nothing to lose by creating a buy thread. Any card must have clear back story to authenticate and will need third party examination by Diana experts.
Japanese Base non holo: $4,000 - $7,000

Other Japanese items: Depends on card
if you do ever locate such a card, you deserve a 1000+ likes on this forum. this is actually one of the most outlandish WTB posts i’ve ever seen. i thought you were kidding when this convo popped up in the past weeks.
