Hologram sticker

I was cleaning my basement and found a Vader that I didn't know I had.  It has an oval hologram sticker on the front, to the left of the "Atari 2600" logo, that none of my other systems have.  There's also a white paper sticker on the lower right of the base with a few numbers and letters written on it.  Is this anything special, or did someone throw those stickers on themselves?

Thanks
