(Personal opinion: this is one of the best looking sheets out there ^^)

Some nice references to the original games:

• Eevee has Celadon City buildings in the background, which is where it could be obtained.

• Snorlax is shown blocking a road, just like in the games.

• Porygon is shown with slot machines in the background, since it could be obtained at the Game Corner.

• Farfetch'd has the Vermillion City Harbor in the background, which is where it could be obtained through a trade.

This Mew sheet is needed to complete the Blue version set. However, since it was only released in 1999, further information can be found on that page
