If you send them the 48 Bowman rookie, make sure that you let them know whether or not you want their hologram attached to your card or not. If you don't want it and don't tell them, you might end up with it stuck to the back of your card.
Here's mine that I sent them about a year and a half or so ago. I sent $100 and I asked for it to be signed "Stan "The Man" Musial" or if they needed a higher fee to let me know, but they didn't comply and he signed it simply as shown.
