[Questions] Pokémon art

[Rich123456789]

I was recently cleaning out my attic and found this Pokémon art that is still wrapped in plastic unopened. There is no name, serial number, addition number etc. can someone give me a little more information on this Pokémon art?

Thank you,

Rich

Wait, just to clarify, this isn't TCG related, right? Or is your picture painted on a card back/sleeve?
