Hi everyone,

I bought a larger collection of autographs from the 50s and 60s which included this Elvis autograph.
Although other autographs are authentic for sure, I am not sure whether the Elvis signature is authentic. I am from Germany and bought it in Germany. It is a "Kolibri"-card and on its back it has a red stamp from the "Elvis Presley and Ted Herold Club Frankfurt", Germany. Unfortunately, I do not have any further information on the history of the autograph apart from the fact that it has probably been part of that collection for some decades. 
It is written with a blue pen.
Would be happy for your opinions.

Thanks!
