We all know and love the CoroCoro Jumbo promo cards that were released in the late 1990s and early 2000s. I personally feel the “Pokemon Plaza” and “Pikachu’s Summer Vacation” cards are some of the most beautiful and evocative Pokemon card illustrations ever. Plus, the jumbo size of these promos is just plain fun 
But here’s the front and back of a CoroCoro Jumbo that hasn’t gotten a whole lot of attention:
This card (which is the same size as all other CoroCoro jumbo promos) was included in the November 2000 issue of the magazine to serve as a checklist for the Neo “Crossing the Ruins” expansion, which had gone on sale a few months earlier.
If you look closely, you’ll see that every single card from the set is pictured, including promos and Premium File cards. There is a little box above the card in which collectors could mark the cards they already had.
Checklist cards are usually rather boring and disposable. This one, however, is a stunningly beautiful exception.
