Help with Clemente card

BuccoFan21

I have recently come across an 8x10 of Roberto Clemente with stats on the back like a big baseball card. The date on the back says 1971 and it is signed on the front. However, on the back of the 8x10 is an advertisement to get a frame for your autographed 8x10. Does anyone know if this is a real autograph or if it may be worth something? I am a newbie in card collecting, didn't know if I should buy it or not.

Thanks,
Dan

I believe they may have been gas station give aways. I would say the autograph is a facsimile.

*Edited to add* Anything like this card from Arco stations? Link
