John Hancock and Benjamin Harrison dual Autograph Card by leaf 2012 oval office Becket

This card is 1 of 1 

It is a 2012 Leaf Oval Office and encapsulated by Becket

Has a beautiful signature of John Hancock on one side and Benjamin Harrison on the other!

I would love to know what it's worth or see if anyone would like to make a serious offer on it?

Thanks in advance,

Nick
