Ella Fitzgerald Autograph Medium

craig1971

Hi all - very new to autograph collection.
I really want an authentic Ella Fitzgerald autograph - and was hoping for advice.
For a plain ol autograph on page from an autograph book, certified by Beckett, what would be a fair price?
vs a Parking stub signed on both sides, one, very small, the other, 'Sincerely, Ella Fitzgerald'. It's a more u nique item, and is likely to pass authentication, but would still need to be submitted.

Is one of those mediums (the note page vs the parking stub) considered rarer or worth more than the other?

Assuming reasonable/good conditions for both - what would be reasonable buy prices?

Thanks for any help. Excited to own a piece of history, but also feels great to get a good deal.
