Any idea what these are?
 

I don't recall purchasing them but if I did personally, it was likely 25 yrs ago or so?

All it says on the front, in small lettering is, Printed in U.S.A that you can likely see?
The backs are completely blank, other than one which reads $3.

Exhibit Postcards.

Thanks Chris.

Any idea on value or if the cards are real or fakes? If I purchased them, it was likely at some type of Flea market?

Unfortunately, I'm far from an expert so I really can't say whether they are real or fake. They typically aren't all that value absent a short print or something odd, since they aren't widely collected.

Thanks again, Chris.

I did some looking and most aren't worth a lot.

The backs of these cards are snow white clean so that is why I am questioning authenticity?
The ones I looked at were all graded by PSA but I doubt I'll go that route with these ones?

If they are snow white, I'm pretty certain they are reprints. The originals had tan-ish backs.

That makes sense, and I was also going to add, until I seen the cards I posted again, that some say "Made in the USA" and others say "Printed in the USA"

I thought one of those would tell for certain, but it seems both statements were used so so much for that.

This thread verifies what you said, Tschock.

Looks like mine are reprints as well. :(
Hopefully I didn't pay much for them back then, and the $3 dollars written on the back of one, is hopefully the price I paid for all of them?
