Some additional photos of the sample lots and other miscellaneous “interesting bits” are posted in Quuador’s thread over here too
EDIT: one of the Pikachu’s even has its own Bulbapedia page: Pikachu (Sample Set 2) - Bulbapedia, the community-driven Pokémon encyclopedia (bulbagarden.net)
And there is a more generic Sample Set page here too, likely with others that were not “officially released” to the public: Sample Set (TCG) - Bulbapedia, the community-driven Pokémon encyclopedia (bulbagarden.net)
