The worth of this old card

[Argon88]

When cleaning out one of our storage room I came across an old football card that was used for a bookmark in a magazine for around 30 years. The card is of Donny Anderson and it has on the uper left hand corner what looks like a signature. And on the top of the card it says 3-D Super Stars. The card is in perfect condition in a little sleave.

Does anyone know what this card it worth?
