The earliest other card is Ho-oh 7/64 in Neo Revelation (2001). That card lists 90 HP, and this one lists 80 HP. The rarity there is Rare Holo, and here it is Promo. Kimiya Masago illustrated that card, and Mitsuhiro Arita illustrated this one. 33 other cards of Ho-Oh list a different HP.

Wizards Black Star Promos set binder is where a full Wizards Black Star Promos set goes. This card fills one slot there. A generation binder holds one card of each species. Ho-Oh can fill a slot in Generation 2 binder (Johto). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
