Save the invoice that shows it was sold to you and shipped to your address.

Your sales receipt with your name and date on it. And the price.

Shipping receipt with your address, box cutout of the model #, and a picture of your original receipt should get you more than covered. Have fun with your new game.

Picked up in person, paid cash w/no receipt, and used box to lay on while working on the car. I really didn't think this through!

I've never had any documentation

There is really no way to prove with documents that a game is HUO. Documents simply prove that you may have purchased the game NIB or from another party. Documenting what happens to a game after it is purchased is difficult to do. That said, the condition of your game when you sell it will be the best fact to convince anyone of where your game has lived its life.

I wouldn't worry about it.

When selling or buying, it will always come down to condition.

Even HUO can become trashed.

LTG : )

What did you buy? If it's great and what you want, you may not sale it. Someone may inherit the "HUO" pin.

I bought an HUO game today.

You don’t need documentation to know it.

It’s kind of like obscenity. You know it when you see it.

Condition is king.

Documentation is interesting, but ultimately unnecessary.

I only have one HUO game. It doesn't have any paperwork with it, but it still really stands out from all the others just because of its condition.

The best thing you can do is take care of the game. Keep it out of sunlight, put down mylar in high wear areas, keep it clean, wax it regularly, change out the balls when they start getting scratched up, add playfield and plastic protectors, cabinet protectors for the legs, and maybe a few other optional odds & ends to help maintain its condition.

It's like a really nice car. Keep it clean and looking nice, do regular maintenance, and you'll be able to sell it for a good price later.

I take pics from delivery to my house, to all aspects of unboxing. Its also good for insurance purposes.
