I love hearing others' opinions! However, before you start commenting, please read this carefully: I welcome opinions but will not obey orders and suggestions. So, please don't say, "Toss that in the trash," or, "Frame the autograph right away," etc. I understand that you're sharing what you'd do, but you can't make me do what you order--what I received in the mail is mine, not yours.
