Pokemon Huddle postcard

One of five promotional postcard sent to those who pre-ordered the Pokémon Crystal game. Illustrated by Keiko Fukuyama and is part of the "Set A" of the post cards¹.

The postcard features Shuckle (of course!), Pikachu, Chinchou, Hoppip, Skiploom, Pichu, Cleffa, Snorlax, Smeargle, and Rattata.

I saw this one called Pokémon Huddle at The Art of Pokémon², I don't think it's official but I liked it!
