Topic: No date or copyright logo on back of SuperMarioBros/Duck hunt for NES

So I was looking through my old games and noticed on the back of one copy of SuperMarioBros/Duckhunt there was no date or copyright logo. So after checking many other copies, which all had dates and copyright logos, I started researching and found nothing whatsoever. Anyone know why this isn't copyrighted or dated?

wow is this a joke or do you really have that?
its a super rare variant.

@Trohs
Can you post the actual pictures of your shady games ?
Maybe we can help you to identify your old games.

Hey, dude.
Be serious in replying. The way you answer his question was Very Disrespectful.

How do I post a pic?

The most expensive game is only worth $70,000

You can take a snap with your smartphone, then upload your photo to imgur.com
Copy the link from imgur to this site with format like this

(img)link(/img)
Replace the ( ) with [ ]

The back of the game in question is my profile pic. Lol. It's SuperMarioBros/Duckhunt

I don't need to identify which game, just why it isn't copyrighted or dated

You uploaded it as your avatar. It's a tiny image.

You might wanna consider buying a new potato.

It would seem there's a few different versions of that cartridge.

Not sure if some were missing the year in the back.

this. is making me laugh so hard...

@ogo79 Wow, that 89 cents I paid for mine in 2001 will sure pay off since I seem to have an identical copy.
(though I only own one copy of SMD/DH. Am I unusual? )
