Well Don, not easy to say. Very tricky in my opinion. It has something positive and looks like was signed rushed in a hurry. Let‘s see what others say.
https://www.ebay.com/itm/Elvis-Presley-1956-RCA-Promotional-Card-si... - this autograph also from eBay and it's very looks like on a signature from this photo (i mean style of handwriting). And I don't believe that it was written by Elvis's hand. So I think they're both not good. Especially I don't like "Presley".
But if someone really decided to buy it, I also higly recommend to spend $15 on Roger's opinion...
