I know that a few months ago someone posted this photo of a Korean Torchic Deck from the ADV days in 2004 looking for more information
An almost full collection of the set has just come on sale locally in Korea and the seller was kind enough to send me a full-res photo of the Torchic card in question. The ADV set has 55 cards in it, so if you look at the card number on the Torchic it looks like there were 3 Korean sets around that time, one for each starter.
And here’s the Treecko!
and here’s Mudkip!
Apologies if this is common knowledge - just thought it would be fun to share!
